On a trip to Maine one weekend, besides racking up many hours of driving, we gained some important insights about traveling with our dogs: 1. The term “dog walk” at thruway rest stops means a strip of ground too disgusting for anyone’s feet or paws. Watch for glass, garbage and other debris, and bring your own poop bags. 2. “Low balance” at two consecutive EZ Pass tolls will mean “No cigar” at the third toll. 3. Try to arrange for a hotel room on the first floor.
