A Little Montana Fall Y'all

Every day, I get to go for a little walk.  There are over 80 miles of trails throughout my town of Bozeman.  Here is the map of trails in case you are in the area!   I plan on checking out every last mile at some point.  Right now I like the more open and less bushy trails because the bears are trying to overstuff themselves before hybernating.  And I am a tastey treat, lol!

The snow will fall soon.  In fact we will have 2 days next week with below 0° temperature.  I'm not sure I am ready for that - or the ice.  What do you guys do in the winter for exercise.  Are you changing anything this year?
