Hot Dog Johnny's in Buttzville, New Jersey, which we typically visit this time of year every year and has been part of our anniversary hike tradition! This is the most well-known of the historic eating establishments on the Route 46 Corridor in Warren County. This stretch of highway is amazing in that it retains so many of its popular eateries that date back to the earliest days of motor touring in America. The original Hot Dog Johnny's opened in 1944 at the corner of what is now Rts 31 and 46,
