I just reviewed a map of Lake Tahoe, and it occurred to me that Barker Pass is completely on the other side of the lake from Zephyr Cove. If we participate in the event in Incline Village, we will need to drive all the way to Tahoma to run Barker Pass, then circle back around to Zephyr Cove to camp. That looks like a lot of driving to me. Perhaps it's better to run Genoa Peak on Saturday instead of Barker.

[edit: I checked campsite availability at DLBliss and SugarPine, but they're already booked.]
