I was in Vail on Saturday, saw 18 deer, two bucks. A 2 point and spike. The 2 point was with 4 does, and the spike with 3 does. They weren't showing any signs of rutting, probably just still hanging around their mothers.
Saw 4 does this morning and 4 does this evening, no bucks with them.
Has the rut started? I don't know if it's really going yet, maybe some pre-rut. That said, Halloween is just a week away and is always my favorite time to hunt, because in my experience there is more rutting activity going on that during late buck. It's not far off!
