NO ATV/ORV or even ELECTRIC BIKES.
Trucks/cars okay, as long as you stay on roads.
ALSO, some of the FIRE PERIMETER ROADS ARE OFF LIMITS, so check, and dont rely just on signs.

AS for ARROWSTONE, i believe road is washed out a short way up from back valley Rd.

Due to the Fire AND ALL THE LOGGING over the years (which is like a barren waste ground on top of plateau!!),
THERE IS A LOT OF WASHOUTS and MUDSLIDES OCCURING.

So, you never know when another road will be missing, but sooner or later, more of them will be washed away, i assure you.
