I noticed the same thing in Vail yesterday. Deer were everywhere! I did a stupid and left the truck with just my binos and walked out to a landing and glassed up a single deer in an area of reprod, couldn't put antlers on it, so I went back to truck to grab my rifle and rangefinder and come back and couldn't find it

I didn't see any other deer near it, so could've been a buck.
Seen about 15 does between 3 and 630. They were out in force! Wish I could hunt today, but I have kid duty. Oh well, I still have late season and late archery to make a connection.
