Eastbay,
sorry to hear you no longer visit the place. I have been going there often lately and have had no problems. People been great, pools and surroundings are to.
That's not say that the disrespectful types never show, we do from time-to-time. Liter and other forms of destruction are more likely to happen in the evening hours at the springs and along trails.
I think there needs to be a new management plan implemented by the U.S. Forestry and possilbly the BLM to. DCSH is basically an unsupervised hot spring and needs one at certain times.
