I was shooting a landscape on a semi barren spit of land way outside one of the Obamacare processing plants when I was approached by two rent-a-cops who informed me I was trespassing on Federal lands and that they would have to take my camera....as it turned out after much heated discussion, it wasn't that I was shooting on Federal land, but that I was shooting over the land to my objective. They still wanted the camera. I just laughed, walked back out to my boat and motored away. When I got to where I put my boat in, there was a local yokel waiting for me, as I knew there would be, though thinking ahead, I stopped at my house (no boat ramp access) and dropped off the camera. I managed to convince them it wasn't "me." After all, I had no camera, did I?
So now, as many federal and other sensitive facilities are off limits to photographers, it appears that even shooting over their lands to another objective is illegal. Big brother is getting more powerful in his scope. Let's be careful out there.
