Yeah exactly. 5 days middle 5 days main would be an incredibly rad trip. Shuttle is cheaper to put in at Boundary/take out Carey Creek, too. I did 5/29 Boundary to 6/6 Carey last year. 3.6' at launch, 10k cfs a the confluence, 32k at the Whitebird gauge when we took out.
SO. Much. fun.
The limiting factor is who can take off that much time. Also possibilities for change of crew at Corn creek.
On that note, pencil me in for a maybe. I just got an invite for 7/1 MFS
