Pines is not as good as it normally is due to the forest clearance going on. Not only are large parts of the off-piste areas out of bounds (in fact impossible to ride - I've tried), but the red has a large diversion too.
I didn't try to ride all the Red today, but when I got to Machine Gun Alley at the bottom of the bike park, the detour sign pointed left and left again up the Blue trail. There were no further signs, so I diverted through the Bike Park and made my own way after that. I met several riders at different times all lost. Maybe some divvy has moved the detour sign?
To get the best out of it as it is, you really need to know where you are.
