There was discussion in other I-10 SC threads about the need for a Supercharger in Fort Stockton and San Antonio to complete the I-10 route. I am familiar with trying to go directly between Ozona and Van Horn, but since I live near San Antonio, I have never thought about making the direct run from Junction to Flatonia without making a jog through San Marcos. The trip, staying on I-10, is 204 miles. The portion of I-10 between Junction and Kerrville is 80 mph. Speed limits in San Antonio are generally 60-65. The rest of the run is 75 mph. Elevation drop of 1250 ft west to east. Obviously wind is variable. Has anyone made this run? It's not in a direction I would normally go, but now that I-10 is completed except for Fort Stockton and SA, there will be people wanting to drive through.
