Oregon Coast route, some just used the wide double gearon their racey -sport bikes and a BoB trailer
others, the pannier route, was taken, or both. maybe the pet dog came along..
did a few long trips with compartmented panniers, the forced organization was useful ,
but once home, less useful , than the open bucket bags
that go on the bike to the grocery shop, and come home with food in them.
& got a nickel off the bill for bringing my own bag, for each one the store didnt use.
