Mooshie plans to continue her trek East on US50E after leaving the Reunion. So, she will see parts I have not seen. I have driven I70, I40, and I20 routes. Interstates are no fun.
There is a Motorcycling best rides web-site that is a good resource to check if it could get you through a state in a great ride or if there is one you could take a break on to enjoy for a little sidetrack. I will have to post the site's URL later.
