Two weeks ago I had a top of a Pseudo Sue growler break off like Mt. Rushmore in my car on the way home from Casanova and assume it was a temperature issue. I need to figure out how to properly manage a collection of growlers because I'm heading to MA in a few months to visit the in-laws. I plan to take a break from family time and ride up to VT and hit the big three breweries in an effort to bring back a nice load of beer back to MN. In that haul I want to have multiple HF growlers in my trunk. What will work to get the growlers back to MA, and then in my trunk for two days of driving without the growlers exploding or having the beer go bad? I have experience working in a sporting goods store cutting and wrapping dry ice in newspaper for campers heading to the Boundary Waters, would a similar approach in a cooler be the ticket?
