Hi sir!
Agree with the truck picture too... that's an awesome one
(for the watermark stuff, at the beginning I was a watermarks freak when I started photog. but the more you get into it and the more you understand that if someone want to remove it, he can do it... my only advice is to put your pictures small enough so nobody can print them or/and make a business with... If it's used by a blog or a web site that doesn't make money with, I don't care, as long as they give me credit. If I find someone using it and making money with, then i send the bill. that's all. my resolution is not more than 960px wide.)
Cool set! Maybe we'll meet someday when I'm back in Denver late summer!
Have a good one.
Cheers
