Tom Goynes has sent out an email about the San Marcos clean-up. It's mostly the same routine as always, but he has suggested adding a section from his campground upstream to Cummings dam and back, and is also investigating trying to clear a logjam of water hyacinth up where the Blanco comes in to the San Marcos. That would require special equipment (especially a conveyor belt for getting the hyacinth into trucks), and may not happen.
Section 2, the long-time HCC section, has lately had more participants than trash. If anyone's interested in attacking an under-served section, I'm wiling to "lead"*. I'll report further developments as they occur.
* or we can draw straws, and the short straw has to be the leader.
