not so much the storage box/bag you keep them in. i have storage boxes on both of my machines… more along the lines of, what goes inside of the rack box/bag that you put the soda into to keep it from rattling around, getting crushed, and getting pierced.
ill start by sharing my technique that has worked so far…
i start with one of these cheapo cooler bags that come with certain types of beer(dont worry, they also work with soda).
i put that in the rack box, and inside of it, i put an insert from a kolpin cooler bag(the kolpin matrix) i was given inside of it.
i can probably fit about 10-12 sodas for the whole group with a bit of ice on top.
it works pretty well. especially if i keep everyone from crushing cans. ive found that crushing cans gives you extra room which lets things rattle around and you end up with cans that get micro holes in them, which results in soda all over the place.
my problem is… my kolpin matrix "insert" is wearing out. the padding is nearly non existent, and it is a bit "funky" and has an odor of stale soda. i cant find an alternative storage solution. i thought about buying some neoprene and having my girlfriend sew up something similar to it, but neoprene isnt easy to sew, and it aint cheap either.
so.. show me or describe me your soda transport ingenuity!
