Sounds like a good idea to me. I think it is great that you are starting to think about it now instead of much later. There is a lot to consider.Brother Bill can certainly help you with some ideas. I would be pleased to help in any way I can. If you need to get an idea of distances, you can take a look at mapquest.com where you can enter the names of any two cities and receive computer generated driving directions as well as estimated travel time totals. Try pluggin in a trip from Detroit to Memphis to see about how long such a trip would take.
Bill and I planned our days so that we were never scheduled to drive much more than 400 miles in a single day. Usually it was less. But we made some notable exceptions. If you will be driving alone, you probably should consider a smaller daily maximum.
Our emphasis was on meeting Mudcatters. Sightseeing was kept to a minimum because of the limitations of time. However, we managed to see some wonderful things. I will be posting a memoir of the Adventure in the near future. I'll be sure to point it out to you.
I think it is perfect that your announcement comes on the one-year anniversary of the start of the Adventure Bill and I had. I wish you the very best.
