An unofficial national holiday will be celebrated as people gear up for Super Bowl Sunday.

The New England Patriots take on the Philadelphia Eagles in the 52nd rendition of the NFL championship game. The game kicks off at 5:30 p.m. Sunday in Minneapolis, Minnesota.

The Kansas City Chiefs were eliminated from the playoffs by the Tennessee Titans in early January, and some people have referred to Sunday’s game as the “Who Cares Super Bowl.”

But it’s still the Super Bowl, the most popular sporting day of the year.

Numerous public and private parties and events are slated in Leavenworth for the big day.

The Salvation Army is hosting a free Super Bowl LII Party for teenagers from 5-9 p.m. Sunday.

The party will include dodgeball, basketball and free food – and of course, the game on television.

The event is for middle school and high school students. Youth groups are welcome.

The Salvation Army is located at 600 Walnut St.

The Fort Leavenworth Dining Facility will be open for a Super Bowl Sunday Dinner from 5-6:30 p.m.

The buffet will consist of chicken wings, barbecue, turkey nuggets, pizza, chili, baked beans and more.

The standard dinner rate is $4.85 per person.

Helen’s Hilltop restaurant in Tonganoxie is hosting a Super Bowl Sunday Chili Cook Off.

Contestants are encouraged to enter their chili in the contest. The crowd favorite wins a cash prize. Door prizes will be awarded to all participants.

The event begins at 4 p.m. Sunday at the restaurant, which is located at 19611 McClouth Road.

None but the brave likely will fire up the grill and have a backyard barbecue. Sunday’s high temperature in Leavenworth is expected to reach only 27 degrees with a brisk north wind of about 20 mph. What’s more, there is a 50 percent chance of a morning snow shower on Sunday.
