We had a plan as we left our hotel room bright and early on a brisk San Antonio morning. We’d park the car at the main visitor center and walk south to our furthest destination at Mission Espada. We’d rent bikes there and return to the visitor center via a stop at Mission San Juan. Then walk to Mission Concepcion and ride back to the visitor center. If we had the time and energy, we’d drive downtown and park, bike out to Mission Concepcion and walk back to our car. If not, we’d complete the walk another day. Sounded like a complex, but reasonable plan. And off we went.
