Parking worries
Mostly vehicle theft. As everyone should know, there has been some major "problems" on top of Skyline Drive with theft.
I once had my windsheild smashed, someone had thrown a large rock though it.I was parked in a pull off, on a road in a "locals" only area over by Stag Hill. I feel it happened because I was not a "local". It seem to work, I have not been back since.
As a responsible MTB'r, I am always concerned about parking in designated areas. Blocking an access gate, parking on private property or in an "unsafe zone" is just not cool.
