My wife and I will be passing through Montana on I-90 on our way from WA to CO in mid-September. Here's what I'm looking for: close to town trail network with lots of green/blue trail options. No shuttling, no lifts. Gotta keep it wife-friendly. Also, I'd rather not encounter a grizzly. I know the odds are low, but still, I'd rather not venture too far into the backcountry. Basically looking for some fun, accessible trails to ride to break up the monotony of the drive. Thanks!
