Lots of good comments and advice in this thread. We managed TotD on Sunday and planned to hit Cherhola on Tuesday (Monday had rain in the forecast, which was accurate) but the Speedster had other plans. The electric fuel pump crapped out about 15 miles from our hotel, in an area without cell service. Thanks to a good Samaritan with a landline, we were able to call for assistance, and managed a ride back to the hotel to get the trailer. I'd thought ahead and brought the generator and winch and had parked on a flat spot, so recovery was simple. Her sister bought a home this summer in Franklin, so we'll be back at least once a year and will have plenty of opportunities to explore all of the twisty roads the region has to offer.
