Scary cause it is sumthing I would of done 30 or so years ago...

I rigged a dryer vent hose to a big cooler that held almost 3 bags of ice... I put one end out the vent window I cut two holes in the top of the cooler and inserted the other end of the vent hose in one... AC... I was an apprentice plumber at the time and we had 2 Country Clubs as customers so ice was easy...
