The issue is that a green sticker can only LEGALLY drive UP TO three miles on a ML3-5 road and ONLY if it terminates in a legal OHV riding area.
I believe that Peirces to T fits that, but that Philbrook to Pierce's doesn't (either in distance and not being a legal OHV riding area.)
Because it is County from Paradise / Magalia to Philbrook (including Inskip) that doesn't qualify either.
So in reality, the only legal place to tow is the Lotts Lake "T", or within 3 miles of it, and ONLY if that is a legal riding area.
Enforcement or not will be the issue.
There are longer range plans to work on a LEGAL way to green sticker all of the way in, but they got postponed due to other issues. - Back butrner, not forgotten.
