Yes Paul,
That trail next to the springs IS the Pacific crest trail. So in other words anyone with a bike and no exceptions will be punished.
It will be OK to bring a horse however. Ohh, and be sure to bring a shovel ! They can ticket you for not having one.
This just goes to show that when you are trying to recreate yourself on your property you are a slave to the feds. By rules that are too complicated for most average people.
Remember , Ranger -- Danger is a good rule when on your property the federal lands.
When I was a child it was not so, they did not even carry loaded weapons like now.
On federal lands the constitution has been suspended, you have no rights !!! GRRR
