Mar 16, 17 looks like it will work!
The best campsites (IMHO) are at the mouth of Moyer Creek, about 5 minutes paddle from the narrows at the middle of the lake and around 2.5 – 3 hours paddle from the boat launch at the south end of the lake. I have base-camped there before and then explored the rest of the lake.
Depending on work schedules and who can come, this could be either 2 nights (Fri, Sat) or just overnight (Sat).
Also thinking this won’t be an official trip, so if you are interested in coming along, post here and then we can take it off-line to sort out the details!
