Hi Lisa. The 20th would probably work, as would the 13th. There is a birthday party Memorial Day weekend for my aunt who turns 90, so that weekend I'll be there. They don't give out 90th birthdays to a lot of people, so that is a little special. She looks and acts like she is in her early 70s but her energizer bunny routine won't go on forever.
My original plan was to meet you in vicinity of Redding, which is roughly halfway between us, but I am amenable to other suggestions. I'd leave here Friday morning, camp somewhere that night within striking distance, then we could meet up Saturday morning/afternoon.
Let me know.
