It started as a way for friends from North Penn High School's Class of 1975 to reunite after entering college.
Some had played hockey as their school sport. Others joined in on the street just for fun.
They remember the Philadelphia Flyers' back-to-back Stanley Cup victories generating excitement about the game.
After that first year, the tradition stuck. And they have no plans to stop.
