THERMOCELL! There must not be to many southern hunters here. It's the only thing I don't leave without and always have a spare.

Thermacell, LRF, and text messaging, in that order. I climbed in a riverfront box blind the other afternoon when the temperature was in the 80's and there must have been 40 skeeters in there, just waiting in the dark. Had to put on my jacket and hat just to make it for 10 minutes while the Thermacell warmed up.
