Hunt at night when it's legal. I've done afair amount over the years, dawn, dusk, night and I've always had a lot of success at night with a spot light. Some say use a red lens but I've never liked them. I use a combination of electronic rabbit squeals and mouth squeals. And yes, hunting when there's a good snow on the ground usually is pretty productive....a lot of times I'll see them cruising or mousing in wide open fields around 12 to 1pm in the afternoon.
