There's good playboatin on the Guadalupe below Canyon dam near New Braunfels, 30 to 45 min from SA, but this year has sucked for rain, and they're only releasing around 200. Hueco springs rapid is great from 2300 to 3500, Common street is good 2000 to 6000, and the hole downstream from fourth crossing is world class at 5000. Right now the best bet is the wave at Rio Vista dam in San Marcos, 45 min from SA, on Thursday after the sun goes, the tubers clear out, and we kick out the lights and install El Tumelo, which changes the wave from so-so, lucky to spin and not flush, to a cartwheelin, splitwheelin, loopable hole. We tried a strobe light last week and it was trippy. Longhorn dam in Austin on the Colorado river is badass 3000 to 5000 but lately they've only been surging 2000 through. If it rains, there's a playpark in Fort Worth, and if it really rains north of SA, the Pedernales has great play from 3000 to 10,000, and 10,000 to 50,000+ is a highwater rollercoaster. Mexican creek, 30 min, has some good play at certain levels, although running the drops like Chingasos, The Big Enchilada, and Shove It is more fun. Unfortunately, its dry right now.
