I've thought of using the search engines, but felt if someone knew of a place that had good access to the Hwy, time savings is worth it.
I'm leaving Sat morning, 6am on the road I'm hoping for. Each day will be 9 hrs hwy time, but getting on/off the hwy for food and fuel will take another hour and the time to fuel and eat, I'm figuring I'll be 12 hrs on the road each day. 600 + miles. Trying to take the most direct route to save time.
Spending only 3 nights in Spearfish, then a nice 5 day drive home. I don't even know if I'll plan the trip home, or just drive that direction.
The "Trip Adviser" search results will give you all of that info,Like location and what's nearby like food. Usually each hotels' site will have a map and directions.
