Living 20 minutes away is pretty darn close (well at least up there - that time might correspond to three miles for commuting B.A.P.s).
Stopping point will, of course depend on progress. Northwest shoulder area of Mount Adams? North of there? We'd love to get close enough to Mr Mud to annoy him, but not yet this trip.
And we'll likely be camping either three or four nights in Cascade Locks, so those food recommends will come in handy!
