I'm going up N. Fork Big Pine Creek on Sat/Sun!
I haven't had much luck landing a permit yet though. As far as Saddlebag lake, I don't think you can camp there: "Backpackers must go past the end of Saddlebag Lake, to Greenstone Lake or farther into the 20 lakes basin area in order to stay overnight. Camping around Saddlebag Lake is limited to the campground near the resort"
