RE: What scent do you swear by?
DPV, I personally am having a little luck with the Buck Fever line of scents from Hawgs Unlimited.
If you do a search for 'scents', using a 30 day search period, you're likely get 30-50 hits and a lot of good advice and tips in there. Use this board first and Deerhunting second. Good Luck.
