A good pro football game is like Ragnarok: it takes place in the dead of winter, shatters the very earth asunder, and involves a lot of Vikings and Giants brawling in an open field. Revel in the glory of football's past with today's Groupon: for $10, you get a regular adult admission to the Pro Football Hall of Fame in Canton (a $20 value). This Groupon is not valid for special events.

The Pro Football Hall of Fame is the "Ballhalla" of the National Football League, where its most glorious warriors, coaches, and officials are enshrined after honorably departing the field of battle. Upon entering the museum, pigskin disciples are greeted (though not animatronically) by a larger-than-life statue of celebrated athlete Jim Thorpe, followed by an exhibit chronicling the early years of pro football, when ragtag teams played to meager crowds with little protection. As you push your way upfield with a series of running plays and hard tackles, you'll find yourself surrounded by walls of glittering heads in the Hall of Fame Gallery, where each Hall of Fame member is immortalized with a bronze bust that eerily chants Super Bowl predictions every solstice at the stroke of midnight. The polish is still gleaming on the busts of Emmitt Smith and Jerry Rice, who just this year joined the storied ranks of legends like Jim Brown and Johnny Unitas. Other exhibits include the Lamar Hunt Super Bowl Gallery, where the most sovereign of football games is given proper retrospection through the display of authentic, recognizable jerseys and footballs from the most momentous plays.

Because attempts to render real football games interactive risks incurring the wrath of Mad Dog Mike Curtis, the Pro Football Hall of Fame thoughtfully allows back-seat quarterbacks to take the wheel with football-throwing activities and video games, or just flex their brain muscles during NFL trivia contests. Famished Lombardi Trophy browsers, meanwhile, can take a halftime break at the Hall of Fame's Tailgating snack bar, where they can devour high-quality grub and play fantasy football by pitting the tackle-breaking abilities of He-Man against the career interceptions of Skeletor. As the fall season approaches with the unstoppable speed of Dick Butkus in a quarterback's nightmare, get emotionally ready for some football with today's Groupon to the Pro Football Hall of Fame.
