Being in San Diego, one of my favorite camping areas is Joshua Tree NP. The bad thing about J-Tree is no trees - back to the tent thing. I've considered using cams or plugs and trying to hang from the rocks. Any of you climber types out there or anybody with any experience in these things have any comments and/or suggestions on either of these or something else entirely. I don't want to cause any damage to the rocks so pitons are out unless there's an EF way of using them.
