After weeks of searching the area, I found a new ride!
Damien and Michelle introduced me to longboarding a few weeks ago, and I really wanted to get one. We looked in San Antiono, then looked in San Marcos, and found nothing. We made a stop on the way back from San Marcos and found this awesome Sector 9 "Uluwatu" bamboo board. Not only does it propel by human power, it is made from a renewable resource - bamboo. Their slogan for this line is "Save a tree. Ride a weed".
Love the board. Went out this morning solo through the park, then again tonight with Damien. Great time!
Thanks to D&M for turning me onto longboarding!!
