We've been in San Antonio for a week. During that time I've used their walking and bike path along the San Antonio River to access parts of the city and just for kicks (I really love my bike). The best part for me has been access to downtown from where we're parked south of San Antonio's downtown. When in San Antonio, if you're a bike rider or runner or love a good walk, the river walk is a must.
Traveler's World RV park, where we took up residence for the week, is located just off the river walk and about half way of the stretch of the riverwalk that runs south of town. There are three missions located south of the RV park and easily accessed via bicycle along the trail. I visited two of the three and Melanie accompanied me on one of those jaunts.
