We've planned this awesome road trip from Florida, to Tennessee, to New York, to Montreal, to Illinois, to South Dakota, to Arizona... My man will be driving the Mini Cooper -I'll be in the passenger seat. (we're both tall) What can we expect? I assume our backs and necks will need support. Any advice for keeping aches and pains away? And what about my fitness regimen? There will be no time for gym visits along the way. I'm a little concerned. Excited about the trip, but a little concerned. Any advice?
