Trail cameras are typically motion detecting cameras that you leave out on hunting grounds to help scout the area. In particular they help you determine feeding times and patterns as well as what types of wildlife are in the vicinity.
Great picture. Santa is bringing hubby a bunch. I found out our neighbor has a ton in his small section in the woods (which hooks into ours and our trails) hence I have learned to be more careful about nekkid hiking.
We are going to set some up to catch tresspassers since we are not there enough.
I've been waiting for the digital ones to get cheaper, I think they are finally reasonable enough.
