Do they float? (It would be good if they do.)
Wouldn’t it be much more plausible to have lost them in a boating accident if they didn’t float?
Egads. Not another boating tragedy. Maybe make some little life jackets for them. Styrofoam (soon to be banned in nyc) and some duct tape ought to work. As long as their not full of extremely high power .223 ammo. You’d need more styrofoam in that case.
