I have a buddy who is hauling boats around the country, mostly west of the Mississippi. He's a responsible and resourceful sort that one could count on not to foul up a set of speakers or what have you. It occurs to me that someone here among us might want to have a nice craigslist find or Polk forum swap meet purchase sent that way rather than the alternatives.
Anyway, his immediate itinerary for the next week or two is Portland to Corpus Christy and then back north. A stop in San Diego is likely on the way down. He's flexable going south but I doubt that he'd deviate much from a direct route on the north bound trip.
Post here if you are interested.
