For anyone interested in joining up, the MacArthur BART is abt 1 mile away from the start and the finish will be the Lafayette BART.
So, if you want to ride along and will come via bART, PM me and I'll give you directions to the start from MaC BART. If you want to ride and will drive to the start, PM Trek420 for driving directions. (if I give those, there's no tellin' where you might end up).
