The Billings West End Wal-Mart will host a fundraising barbecue Saturday from 10 a.m. to 4 p.m. to support the Big Sky Honor Flight.
Sen. Max Baucus is scheduled to help out at about 12:30 p.m.
The event will include burgers and some special guest "chefs" flipping burgers throughout the day.
Organizers are working to raise $150,000 to fund the inaugural flight that will take 100 veterans to the nation's capital.
A Montana chapter of the Honor Flight Network was activated in October to honor the state's World War II veterans. Thirty-three states now have the Honor Flight program. The purpose is to take veterans to the World War II Memorial on the National Mall free of charge on a chartered flight. Montana has the second-highest number of veterans per capita, behind Alaska.
Students have joined in the fundraising efforts.
Earlier this month, Washington Elementary School students raised $1,515 in one week. Laurel Middle Schoolers have raised more than $2,500.
Wal-Mart has been taking donations for more than a month, and the Shepherd Lion’s Club will match all donations up to $1,000.
