Went MTBing in RCP earlier today. Unlike the trip reports there, I ascended then descended, I didn't just do a one-way. Took eastern route (up the steps made with railroad ties to the overlook with the benches) instead of the route suggested as Ride #3 in the excellent book Mountain Biking L.A. County (Southern Section). I heartily recommend you buy that book. Heck, buy 100,000 or more, so I can get 8% instead of 5%. I biked to the start of the path to the "low overlook," then I had to carry/push the bike up to the overlook. I was able to bike the rest of the way to Mulholland, then to the "high overlook," and then I came down using the western route featured in the book. The western route is paved starting halfway; next time I'll reverse the procedure. I saw neither celebrities nor guys having sex in the bushes.

I think I'm going to get a cheap old external frame backpack at a garage sale and convert it into a carrier for the bike. If that works out OK, I could take the bike with me to do something like Strawberry Peak. Doing third-class rock with a 30 lb. bike strapped to my back is strangely appealing.
