I don't think you can hunt them during any other time than the fall/winter if you are concerned about snakes, but on a mild day like many we have had this year you would need to watch out.

Never hunted them. I've seen snipe/woodcock in swampy areas and along hardwood creek bottoms. I've seen snipe on occasion in shallow flooded fields. You never see them until they've seen you and they fly off and squawk right when they get up.
