Are we likely to have difficulty getting Robinson Creek (aka Twin Lakes) permits walk-up the Thursday before Labor Day? I have no idea what the quota there is, nor how popular that trailhead is, and the USFS web pages are no help (unless I missed something). I'll phone the Bridgeport ranger post on Monday, but we're trying to make plans this weekend, so any hints would be helpful.
As a general comment, it's depressing that we are in 2012 and it still isn't possible to book permits for Yosemite or national forests online with a proper availability calendar. OTOH, I suppose it's one less thing for David Tran to hack/scalp...
