I'm ignorant about the best times for burning so educate me.

IMO it would seem:

Winter - too rainy and crappy
Spring (now) - drier and young-of-year not born yet (other than coyotes, and f'k those)
Summer - hot, green foliage, young-of-year, humidity
Autumn - hunting seasons, fawns, poults, upland birds, perhaps more humid

I don't know, though. Spring would seem the best time. Turkeys re-nest if the opportunity is there. Most folks, at least the intelligent ones, burn in patchwork don't they?
