Have not been there lately, but guess is the nicer end of Oct. weather has them setting in all the local reserves...i.e. North Potholes, Winchester, Frenchman Hills etc. Too much bluebird weather. Typical for end of Oct. and first week in November in the north basin.
I'd be hunting next week though...just before Veterans day and after. Always good for first waves of northerns. Most think it occurs later by 1 1/2 to 2 weeks later.....not. Get in on the early action.
