Faded Sign Challenge

I found this very faded sign at Road America race track in Elkhart Lake Wisconsin. I tried to read the sign before taking the photo but was unable to read it. The photo above was not altered in Photoshop except for minor curves.

I played with the photo in Photoshop and was amazed that by using a filter I have never used before “find edges” I was able to read the two lines of text.

Anyone want to take a shot at what the sign said?

Good luck.
