Finner,
I was just about to post that same question. I saw multiple bucks the past morning that were freshening scrapes and rubbing trees and reacting to my rattle bag but I never saw a doe so I don't know how they are reacting to that. Based off the reaction to the rattle bag I thought a buck decoy... but on the other hand I would think their main goal is to find the does so I'm not sure which to use. I would think the doe is the "safest" bet as far as not scaring deer off but I'd like to hear from other peope who have used decoy as I have no experience with decoys.
