Alabama or Georgia would be good. I think last weekend's marathon showed me the advantages of staging it near the home of one of the participants, so we should keep that in mind. We should also give some thought about what the course should consist of. For that matter, once we know what an appropriate course would consist of, I bet we could find a suitable place almost anywhere.

Also, since I have proven that the HCH tank will hold at least 16.027 gallons (that is what I once put in, and it had not yet run out), and that it can do 90 mpg over the Prius marathon course, I think our target should also be at least 100 mpg for a whole tank. That means 1600+ miles. That will take some time, probably a lot longer than the Prius marathon's 48 hours.
