When I hunt in northern New England I track when there is snow. If there isn't snow on the ground, I'll over-watch in the early AM and late PM and still-hunt from 9AM to 3PM. I mostly hunt in the Connecticut River valley in the towns of Haverhill, Piermont, Orford, and Lyme on the NH side and the towns of Bradford, Newbury, Ryegate, Barnet, and Waterford on the VT side.
