You don't have ANYWHERE else looking at all those woodlots that you can try on N wind?
You're kidding right?
For the record I wouldn't have picked where you sat tonight had I seen the terrain.

LOL
Think security type cover with good trails through them to those fields, bucks aren't that dumb. They're probably bedding in the same type of cover they will use to actually enter any remaining food fields.
If you're not findning bucks right now it's probably because they're where you don't want to go. That or they're just snoozing til' dark. LOL
