Fletch, thanks for the local info. Is the north-to-south direction the easier way thru Poker Flats?
I would agree that North to South thru Poker Flat would be easier. Here's some trouble we had going South to North trying to climb out of Poker Flat on the bush pig DR650, not long after some knee work...
Better yet is a fantastic singletrack that departs Poker Flat and heads back towards Downieville, the "Sunshine Trail" it goes to the Gibraltar Mine and connects to the east end of Chimney Rock Trail. It's on that Downieville singletrack vid, and it's a workout!
