I'll level with you, I haven't searched every pixel of these pics for signs of Photoshop. It's not impossible that some sneaky so-and-so subtly doctored one of them and made the unreal seem real, but I'm giving them the benefit of the doubt.
Because all of the pics in this marvelous collection hit that sweet spot of being just wild enough to surprise us, but not so wild that they're impossible.
Enjoy!
