Day 3 Sargents Mesa (Segment 16/17) to random campsite (Segment 17)
Thermometer said 38f this morning but it felt colder. Probably wasn't though. Lots of activity in Sargents Mesa last night. Heard elk bugling often and thought I heard a dog at least once. Definetly heard some coyotes around 5 or 6. They sounded close.
Today was anticipated to be dry so I carried alot of water. Usually the pack gets lighter the longer you're out due to lightening the food bag. However, when you have to carry extra water you don't realize that benefit. I met some hunters who gave me an extra bottle of water and took my trash. They actually knew what trail magic was and it was very much appreciated!
If you spend enough time hiking, it is inevitable that you will eventually take a tumble. There were alot of rocks today and I did fall while hiking downhill. No injuries though.
A possible water source at Razor Creek was dry where trail crossed but I found a small pool upstream several hundred feet. I was able to dip and fill 32 oz bag. Enough for a hot meal and some extra for tomorrow. I continued hiking but once again stopped early for dinner around 3. Freeze dried spaghetti was on the menu. Typical freeze dried meals are more expensive but easier to prepare. They are also better tasting than tuna packets and creamy noodles of some sort.
After dinner, I made it up and over a few more bumps. Kinda steep but not too long. I found a campsite maybe 1/2 mile before where I planned to stop. A few hikers passed by quickly in search of water.
While hiking 15.4 miles today, the temp got up to 80. Nice increase from the morning.

Insect wings are adult outgrowths of the insect exoskeleton that enable insects to fly. They are found on the second and third thoracic segments (the mesothorax and metathorax), and the two pairs are often referred to as the forewings and hindwings, respectively, though a few insects lack hindwings, even rudiments. Insect wings do not constitute appendages in technical parlance, as insects only have one pair of appendages per segment. The wings are strengthened by a number of longitudinal veins, which often have cross-connections that form closed "cells" in the membrane (extreme examples include Odonata and Neuroptera). The patterns resulting from the fusion and cross-connection of the wing veins are often diagnostic for different evolutionary lineages and can be used for identification to the family or even genus level in many orders of insects.
Fully functional wings are present only in the adult stage, after the last moult. The one exception is the order Ephemeroptera, in which the penultimate instar (also called the subimago) possesses well-developed and functional wings, which are shed at the final moult. Wings are only present in the subclass Pterygota, with members of the archaic Apterygota being wingless. Wings may also be lost in some pterygote clades, such as the fleas and lice.
The wings may be present in only one sex (often the male) in some groups such as velvet ants and Strepsiptera, or selectively lost in "workers" of social insects such as ants and termites. Rarely, the female is winged but the male not, as in fig wasps. In some cases, wings are produced only at particular times in the life cycle, such as in the dispersal phase of aphids. Beyond the mere presence/absence of wings, the structure and colouration will often vary with morphs, such as in the aphids, migratory phases of locusts and in polymorphic butterflies.
At rest, the wings may be held flat, or folded a number of times along specific patterns; most typically, it is the hindwings which are folded, but in a very few groups such as vespid wasps, it is the forewings.
How and why insect wings evolved is not well understood. Three main theories on the origins of insect flight are that wings developed from paranotal lobes, extensions of the thoracic terga; that they are modifications of movable abdominal gills as found on aquatic naiads of mayflies and that insect wings arose from the fusion of pre-existing endite and exite structures each with pre-existing articulation and tracheation.

As I get older, I get smaller. I see other parts of the world I didn't see before. Other points of view. I see outside myself more.

We came across an interesting oddity from the realm of consumer electronics: a fake seven-segment LED display. Just for fun, we made our own version too.

At any one moment, Thornton's video depicts seagulls flocking near the long-defunct-but still-standing-Parachute Jump ride at Luna Park in Coney Island, Brooklyn. This scene is rendered in an array of different media, from black-and-white to color film, broadcast television to digital video, phonography to synthesized audio, all produced through digital manipulation. As this tour of historical formats and infrastructures unspools, Thornton foregrounds the ways in which technology both shapes and is shaped by our understanding of time. Built as an engineering marvel for the 1939 World's Fair, the amusement park ride is resurrected as a virtual rumination on obsolescence and enchantment.
The steel girders that closed the centre span were lifted and fixed in place earlier this week. Concrete deck panels were lowered into position using gantry cranes positioned at the end of the centre span. Soon, crews will start pouring concrete to cast those panels in place.
Elevated guideway segments cast at the precast concrete facility.
Once complete, these segments will be transported to a storage area using a rail mechanism as seen in the photo.
I didn't want to disassemble the display so I made the front brackets seat behind the screw heads (they just needed to be loosened a little).
