We don’t fully understand the “Baby On Board” signs you see on minivans all the time. It’s not like we go around playing demolition derby until we see a car with that bright yellow sign and then ease up. If we’re going to start putting warnings out there for other drivers, we might as well continue with the other precious things in our life, namely, our beer. Growler On Board is the perfect holster to keep those jugs of fresh brew safe from injury on their transport home from the store, bar or brewery. Besides, even if you drive a tank, there’s no way a growler is fitting in your cup holder.
