Just like jimmya said. I put out a scent holder usually 15 yards in front of me (upwind) with doe esterous because I use the 'Can' call alot so I want to smell like a doe in heat if I'm going to sound like one. And I'll put out some buck in rut scent on any rubs I find around so the bucks will think there's a new guy in town flirting with their girl. This works good with the old grunt tube and rattling antlers. Especially in prerut. But now that we're in rut and post rut, I'll stick with the 'lonesome doe' combo.

KEEP IT LEGAL. KEEP IT SAFE. OR WE MAY NOT GET TO KEEP IT AT ALL.
