When you consider the cost of gas, the waning patience of hungry passengers, and the likelihood of traffic, driving halfway across the state to Hopkinton for a particular food doesn’t really seem worth it. Until you try a Snappy Dogs hot dog, that is. Located a few miles south of the Mass Pike, the little red trailer sits in the corner of a parking lot behind the local mom-and-pop grocery store. A wooden sign painted with a red hot dog hangs over the road, swinging as cars rush by on the old highway. Customers look at the daily special described on a leaning chalkboard and queue up on the sidewalk. The menu is basic, but also well-rounded, including three sizes of all-beef Pearl hot dogs.
