JL as most will agree it's hard to hunt and photograph at the same time. that said i have my camera with me every time i step in the woods. like Beau, i will break the camera down for transport and then when i get to the spot i'm going to hunt i will get it out and set up to use. i use a screw in hook to hang my camera on while hunting.
using a daypack or backpack i don't worry to much about breakage, just getting wet. the ziplock bags take care of that problem. then stop in at your local post office or UPS store and get a piece of bubble wrap. just roll up your lens and camera body and place in the plastic bags and you are set.
Phil do you have a web address for those "Think Tanks"?
