CacheDrone: Sadly this listing must be archived. And it is important to note that this is not in any way at all the fault of the Cache Owner, who did state clearly that public vehicles are not permitted access to this private road. But due to repeated times where geocachers have ignored the that this is a private road, blocking the road with their vehicles and such, this is the result.
It would be my suggestion that the CO create a new Multi-Cache that makes people walk along this section of trail instead of taking a vehicle there. A several stage Multi, if properly designed, should clearly show that walking to each stage is the ONLY way to access this section.
