Just because the seasons are changing and there's some snow in the mountains doesn't mean there isn't still plenty of time to get out for a great hike in the Bozeman area.
I am a champion of Bozeman. However, the City of Bozeman (and Mother Nature) never fail to screw me every Fall when it comes to picking up my leaves that I dutifully rake for the City to pick up. Why? Because I live in the 'hood.
