After leaving Yellowstone after dark, we could have just driven a bit and found a hotel, but my husband was anxious to see Glacier National Park, and full of energy to drive, so we drove through Montana all night. This involved me periodically waking up to whine about how this was a really bad idea, how I could never sleep well in the car, how we should really just get a hotel, and then promptly passing out for another couple of hours. When I woke up again, we were in farmland full of cows and horses and deer wandering all around the road. Have I mentioned yet, the theory that we've seen most of the cattle in the western hemisphere on our trip (including the part to Brazil)?
Glacier National Park was still very snowy, but the Going-to-the-Sun Road was still open half way up, so we drove up it away.
Triple Divide Peak is were the water flowing one way flows to the Pacific, another way to the Mississippi, and a third way flows to Hudson´s Bay. It was time for us to flow away from the Pacific as well.
