Punkin’ Chunkin’
The town of Rehoboth Beach, Delaware, is a popular summer vacation spot along the Atlantic Ocean coast. When Labor Day passes, most beach people leave until the following summer. However, many return in the Fall for the annual Punkin’ Chunkin’ festival. The main attraction of this weekend is a “World Championship” contest to see which team of amateur engineers devised the best machine for launching pumpkins a long distance.
