Right now, his newest hobby that he started, is collecting 'growlers'...So far, its only a small collection, with just 4 'growlers'...but at the last place he got his most current 'growler', he also got a little insulated bag, made expressly for slipping tightly over the 'growler' and keeping the beer cold, until you get home...this eliminates the need for having to haul around an ice filled ice chest in the car...
