Route recommendation?
 

I am planning on doing this trip here in the next few months, it will be from LLano to Port Aransas. I plan on doing the ride in 6 days but may do it in 4-5 days. The route that I am planning to to take is below. I am looking for possible other routes that may save mileage, less traffic, cool stuff to visit, what ever. I have relatives in Johnson City, Buda, Maxwell, and Floresville that I can possible stay at, but I am planning on camping most of the way. Texas law does not allow cyclist on freeways, so I 37 is out.
