Before someone jumps on me for using cameras, they are the only high tech item I use. My camp is 3 1/2 hours from home. Home and job don't allow enough time to scout these locations. The cameras aren't checked until mid day so they don't often effect how I hunt. They just show me what went by while I was gone during the workweek. (And clearly I'm not hurting the population!) Also, I am sure they are missing deer. So they can actually make you think no deer have passed, when they have!
