Our wonderful trip ended messy, literally, so I'll talk about this part first, with no intention to spoil the thread. Our black tank valve failed twice before, and it was supposedly fixed two weeks ago, but, it wasn't, and you can guess how I found out.
Until we came to that messy ending, we had a fabulous time. We dry camped for two nights at Laguna Campgroud which is located at ~4000 ft in Cleveland National Forest in SoCal. All the reserved sites were full, but we were lucky to have one of the last two first-come-first-served sites. Sites are very spacious, far enough from adjacent sites, in the woods. Beautiful moonless starry nights, wonderful hiking trails. The temperature was crazy, it went from ~90 during the day to ~50 at night.
One of the highlights - we had saved someone from potentially a big trouble. While hiking in the middle of nowhere, we ran into a lone hiker who was desperately lost. She was in her 60s I guess, and she told us she was just not into cell phone and Google map etc. So I pulled out my cell phone (luckily we had signal) and showed her on Google map where we were and where she should be headed. We walked her back to the trail she was from. Everyone was happy in the end
