Years ago we'd transport between dams in 5gal buckets on the back fo a quad... wet work.
The guys started putting a handful of leafy tree branches in and voila, the water stopped popping the lids to soak us.
Give it a go?
I need to do a COVID downsizing move from office to home this month; only 20minutes, but mostly on a not-so-great country road. I've got the original styrofoam boxes the fish came in with their tight lids, but no appropriate bags to go inside - I will be adding leafy branches.
