I have one road trip last yr from smokies to rockies. I was supposed to visit G.canyon at the time , but couldn't squeeze it in. I was wondering if some one could suggest a scenic route to drive through from st louis and also any good stop overs where we can spend half a day before hitting the road. Last road trip we mostly took county roads as I wanted to see the small towns and country side. We did not really plan that well as we spent most of our time driving and did not really stop along. We camped most of the time and used rest areas on interstates to nap. I realized latter that these places are not that safe.I am open to any suggestions. Thank you in advance.
