I planning a ride to South Padre from Lexington for this spring. Mainly secondary highways, may take the Natchez Trace for part of the trip. Will probably bounce around on the way home and catch Austin, some hill country, and whatever else justifies a stop. Any suggestions for good roads, routes, eateries, or other things worth seeing would be appreciated. I know it's 4 months away, but it beats staring out the window at the crappy weather.
