Thank you for creating the RWGPS; I have not worked with that system before and I do not have an account.
The route is very similar to what you posted. We didn't ride on Old Mississippi 7 after MS-7, we just turned directly right onto MS-7 (the road with the bridge, as I call it). I did not notice there are TWO "Co Rd 103" right next to and parallel to each other! We took the second left "Co Rd 103," I believe. The other roads may be gravel, it is hard to know.
I'll be glad to be the "ride director" as it were; of course, I always bow to a vote or those with better jokes. Barry, just let me know if there is anything in particular I need to do (such as sign in sheet, etc.).
I am going to suggest a start time of 7:00 am, just after sunrise. How does that sound?
