Hmmm, well, I missed a calendar item... our ward campout is on, you guessed it, the 20th and 21st...
I am pretty sure we are not going to stay up there overnight, but that would take out Friday, the 20th. I think the 21st would still be OK, though.
I'll check for sure, but it looks like the 21st is the better day for me at this time.
