We will be Speedstering up to Petit Jean this Friday for the 64th Annual. I haven't been in 40 years; used to go every year. It's a 350 mile drive from Madison thru the Mississippi and Arkansas delta. You don't get into the mountains (small m) until past Little Rock. This the largest show/swap meet in the area. Used to make hotel reservations on the 2nd of January to be sure you could get a room. Somehow, Candy was able to book ours 3 weeks ago due to a cancellation at the Lodge.
MOTTA (Midamerica Old Time Automobile Association) is based in Memphis. This is not a European venue; mostly American made, but I would bring whatever sports car I was driving, at the time, and was always well received.
The highest point is Magazine Mountain, 2,753 ft, that's about 2,000 ft. higher than Mississippi.
