I agree with Rob. One of my local buddies (who I believe) watched a pair of 2.5 year olds go at it full bore while glassing just the day before yesterday.I don't think this is the most common time for this to be happening, but deer don't think to themselves whether it's late enough in the seasonto be kicking some other deers butt...........if they feel they need to establish their dominance on eachother, they are going to do it when opportunity presents itself.
