In case you care just remember that Vallecito is in a wilderness area and motors are not allowed.
I found this out in 98 when I went to cut a log out of fuzzy bunny. On my hike up i came across an old fucker who claimed he used to work to the Forest service. Anyway, he saw the chainsaw sticking out of my pack and blocked the trail and told me that i could go no further. We exchanged words and i kept going.
When I got back to my car a forest service ranger was there waiting for me. I ended up going to court. Nothing happened because no one established that i was in fact in the wilderness area.
Anyway, be stealth.
Oh yeah, the judge told me that if i were in the creek cutting out wood that I needed a river improvement permit.
