Ah, The HMS POOP DECK, a fine seaworthy vehicle.... Every year, during Golden Days, Fairbanksans divert a little duct tape from their home repair jobs and use it to create interesting watercraft. The Red Green River Regatta is an annual event that I always look forward to... This year, we created a two-seater outhouse, and floated it down the chena river. Surprisingly, we made it the entire distance without falling apart... :)
If I recall correctly, someone had rigged up a vehicle (yes, a car) that didn't quite make it the distance. Not surprisingly, The entry form specifies that you're responsible for fishing out your craft if it should sink...
