RE: What brand of trail camera do you use?
I've used quite a few trail cameras, at the moment I have another two on order from Nature Qwest (Jeff) haven't gotten them as yet, but I "expect" they will be the answer to all the various problems I've had with trail vcameras.
Buckeyebuckhntr has summed up the DC-2BU LR cameras perfectly---they are good trail cameras--but they do have snags.
Since I've not tried the newer trail cameras on order (Samsung 4.0 IR& Sony S40 4.1)--I'll have to say at this time the LR DC-2BU is the best of the lot I've used ---so far.
