I still have to get that crap out of there Tom. I can only imagine how annoying it would be on the water with all those little bb's flying around. LOLSeen everything from styrefoam popcorn , inner tubes ,flat green "beach balls" "blow in constuction foam" and recently a live cat Gunslingers, Rogers had the remains of thousands of foam BB's etc etc floatation as you suggested or thought is the key ! these boats had testing standards (sinking swamping etc) the manufacturers had to submit to for the various length and size mine has "air"
btw took days but we caught the cat
