A great lens indeed. I liked the 10-22 on crop better then I like the 16-35 2.8 II on FF.
Here an oldie (2007) taken from a driving car in the Serengeti. EOS 30D, EF-S 10-22 @12mm, ISO 200, 1/640, f/9
And another oldie (2010) from Yellowstone (I believe it was Mammoth Hot Springs). EOS 30D, EF-S 10-22 @10mm, ISO 100, 1/250, f/8
