That's some pretty nice looking deer and that buck looks like a shooter. Good Luck and hope ya get one. I am going to post some more pics of a couple that I glassed a few days ago.
About the whole "trail camera" thing, I don't own one and I get some nice pics form just a digital camera that I always carry with me. It works well and if you can get one like mine that you can turn the shutter noises off and pick your type of flash. In my opinion, nothing can beat ACTUALLY being there for the pic.
