I was 19 when I got married and the groomsmen and I were kind of upset that we were not gonna be able to get tanked at my reception. O' Contraire Monfraire, My best man came through for us as he showed up with one of these beauties iced down in the back of a 92' Berretta. Hooray, the night was saved! My dad asked why we kept going out to the parking lot that night, I think he new but was cool with it. Hooray beer!
My buddy had a mid '70's Mercury Marquis back in the early 90's. The beer ball was kept in a box with ice in the trunk. We modified the back seat (read: cut out a hole) so we could reach in and pump it. Then added some hose on the tap so it could stretch to the front seat. For passenger use only of course.
Semi-legal antics usually ensued.
