Bozeman is awesome. Enjoy your trip. Simms just broke ground on a new factory which is going to have some awesome features for walk-in visitors but it won’t be done yet, obviously.
Try to get to their farmer’s market if it is open. There’s some great eats to be had there. Montana Ale Works on the main drag is a nice if upscale bar. It’s on the east side of Main Street, not far from the dirtbag hotel I usually stay in.
Absolutely have breakfast at Main Street Over Easy–it is one of the best I’ve ever had and that includes France.
