A few years back we parked outside a gate beside the Mamquam FSR. That gate intersected the Shannon Creek FSR.
In the early 2000's, the road was closed due to a bridge flood and out of service for 2-3 years.
We hiked up to do SkyPilot and when we returned, my car was gone. Luckily, some dirt bikers were in a gravel field below packing up and gave us a ride to the police. Once there, we discovered that the BC Forest service had towed us. They could have moved the car nearby knowing people were in the mountains but instead, towed it to Squamish leaving the 3 of us in the woods at 9:00pm in the dark.
Don't bank on authorities caring about the person who owns a vehicle parked in the wilderness, plan on bringing a cordless grinder next time!
