Today in Patriots History – August 15th, 1971 – First game ever at the brand new Schaefer Stadium. From Patriots.com:

The Patriots make their debut at Schaefer Stadium in Foxboro. Gino Cappelletti kicked a 36-yard FG for the first points scored in the stadium as the Patriots topped the N.Y. Giants 20-14 before 60,423 fans.

Constructed for a mere $6 million, Schaefer Stadium (Later, Sullivan, and then Foxboro, Stadium) would be home to the Patriots until that snowy night in 2002 when Adam Vinatieru closed it with his overtime field goal against the Raiders. Some nice synergy there, Cappelletti with the first points in a preseason game, Vinatieri with the last points in a playoff game.
