DITTO, Chuck, on the two bucket system!
however, that is usually when i pruchase dozens of eels
and am planning on fishing for two or three days straight and
don't want to have to keep returning to the B&T. they ride just fine
in the passenger's floorboard; from there i'll pull 4 or 5 for
the softsided cooler to take to the rocks of an udl,,,,,,,,,,,
i also use the bubbleweed, the only difference with the ice is what the Mayor of CTown once showed me,,,,,,,,,,,,,,i place a bag of ice on top of the eeeeels and change the buckets often. i also use black buckets, i dunno if there's any science to back it up, but it seems to add to the calming factor
~~along with the bubbleweed, of course
here's sum pix of my softsided cooler insert, seems to work for me.
be sure to wet the "slime drainer" with some cool tap water pre-eeeeeels.
