Not long after getting underway this morning we came upon a police officer who had closed the road we wanted to take; seems there was a marathon underway and we needed to detour around the town of Wynne to avoid it. This caused us a bit of navigational confusion for a while, but eventually we found our way on to AR64 as required. By midday we were racing along the I40 northern bypass of Memphis surrounded by trucks and Saturday shopping traffic. Not our favourite style of travel.
Fortunately the traffic reduced after we left the Memphis area and we utimately found a camping place at Natches Trace State Park a few miles south of I40 in Tennessee at exit 116. A very nice park and campground.
