Tubers float down the Delaware River near Frenchtown, N.J. on July 27, 2020. Greg Crance, better known as the Famous River Hot Dog Man, has operated a floating hot dog stand in the middle of the Delaware River since 1987. In 2003, Greg Crance purchased his own tubing operation, Delaware River Tubing, upriver in Milford. He says he gets tens of thousands of customers per summer, and employs about 75 locals who grill hot dogs, drive school buses to transport tubers, and corral them to the exit. He’s not shy about trumping up the river, either. “You can have as good or better experience than going to a private island in the Caribbean,” he said.
