My husband and I have been throwing around the idea of a road trip to hit up different state/national parks. We both enjoy hiking and instead of staying in hotels/motels all the time, figure we can stay places we can set up our tent-hammocks and stay over night. Ideally we would be able to make it to Glacier Nat'l Park, but I know that Montana is a bit of a reach. Realistically, starting in Pittsburgh on a Friday afternoon and returning on a Sunday 16 days later, where do you think we could visit? What would be the best route? We don't have any preferences really, just to see some gorgeous state and national parks, do some random hiking and camping, etc.
ETA: Time of year is relatively flexible.
ETA2: Also would possibly stop in the Twin Cities to visit family, but more of a stop on the way through for a hot shower and dinner, maybe a little hiking.
