"Not a real grown-up"

I'm really getting into digital photography - current kit is a Canon 40D + 24-105mm L F4.0 IS lens, a Canon 70-200mm L F2.8 and F4 IS lens, plus a Canon 100-400m L IS lens and a 2x extender bought especially for the long-distance Space Shuttle shots! Thanks for looking at my pictures - I hope you find at least some of them enjoyable.
