No you don't need to prove it.. I just figured you have the d50 there. We do have the military base section for you guys to use and abuse in any way you see fit. So you can't take pictures. That sucks. Fricking government and there regulations. If you can take pictures please put them in the military base. We love shots of the cool things you get to play with over there. Once they get back here all the attachments that make them cool are gone.
