Wish I could help... but I’m not going. Having knee replacement next week, and until I do, standing for more than 10 minutes isn’t a good idea).
Amtrak isn’t a bad option. Try FReepMailing alice_in_bubbaland, I think she wanted to go.
Before doing knee replacement I am going to try to do physical water therapy.
Good luck are you doing the regular or Minimally Invasive?
