We headed across Idaho on Rt. 90 and that route was a bit mountainous. I do not like cliffs and drop-offs so there were a few spots that were not to my liking! The vistas were something to see, but I was glad when we got down to flatter ground.
Stayed at a KOA for the evening and Peg took advantage of the pool they had by taking a little evening swim. Tomorrow we follow the Columbia River to Portland!
