For starters, I'm in NC, just north of Winston Salem. My friend wants me to come over to his place one night next week while I'm home for spring break and see if we can thin out the groundhog population. Seems early to me, but I've read online that they come out of hibernation in march-april to mate. What are you all's experiences with seeing the first woodchucks of the year? Do they need unseasonably warm weather to be out early or is it just a biological clock sort of thing where they come out at the same time(for a given area) no matter what? I figure it'll be a blast(literally) whether there are any woodchucks in the crosshairs or not. I'm just curious.
