For some one that claims they aren't paid you sure are pushing this 200 dollar broom handle
if your in a club nobody should touch anything that aint theirs. its not anyones business about the camera but the owner. no one should screw with it whether its been there 4 weeks or 4 years if it aint theirs. Id be pissed guy that removed them probably has a good buck in the area and wanted to screw up your hunt.
This man is correct. Your club Pres. Knows who's got them night even been him. Either way he should have forked over some info. They've seen some good deer on your camera and have now deleted the cards and will probably hunt those spots this year. Start calling the other members and see what they say.
