The family just booked the 4th of July week at the North 40 Lodge between Whitefish and Columbia Falls. We'll be just outside Glacier National Park. I will quite likley have the road bike along. I won't have a mountain bike. I've read a few things in guidebooks about cycling the park and area. I know about the cycling limits on Going to the Sun Road. I've read some about possible construction along Going to the Sun this summer. Anyone with local knowledge have some tips, ideas, or advice.
