Hi,
My husband and I go on short road trips about every two months to visit reletives and friends. They take between 2 to 6 hours. We have to stop every hour for about 5 or 10 minutes so I can stretch and walk a little bit. It makes a big difference in how I feel when we get to where we're going. My husband does all the driving. I live 2 miles from the grocery stores and mall, and that's pretty much all the driving I can comfortably do. Good luck and sorry I couldn't be of more help. Take care.
Hugs,
Pat
