Looks like Sept 11-14th is firmed up. So far Cargo7, my brother on my B6 and I. We are planning to meet somewhere around Colville or Republic and make our way down around Mt St Helen's.
If anyone else is interested, let me know, and we'll work out a more definite plan.
Sorry Red...Sept 24/25 is now not available for me, so we firmed up the first date.
