My husband and I are planning our first trip out west and have chosen to do it by road. We have 15 full days to use for our trip from the day we pull out of northwest ohio to the day that we need to be back. We would like to go to both Glacier National Park and Yellowstone National Park. So, Montana and Wyoming are on our list and we would also like to work in a few other stop overs in between. Maybe North or South Dakota, etc.
Can anyone give me suggestions for either 1) a suggested route with stopovers/sights, 2) a resource to use to come up with a plan? This is overwhelming and we want to make sure that we use our travel time wisely and also take in any "must sees".
