The Los Alamos Valley Men’s Club extends a heartfelt thank you to the 1880 Union Hotel, our Title Sponsor for the 80th Anniversary Los Alamos Old Days, September 25–27, 2026.
Few places represent the history and character of Los Alamos quite like the Union Hotel. Its presence in our community provides a fitting connection between the town’s colorful past and the traditions we continue to celebrate today.
The generous support of our Title Sponsor helps LAVMC bring Old Days to life, from the activities on Bell Street to the events, entertainment and traditions that have brought generations of residents, families and visitors together.
As we celebrate “Boots, Buckles and 80 Years of Memories,” we are especially grateful to the 1880 Union Hotel for its commitment to Los Alamos, its rich history and its community spirit.
Thank you, 1880 Union Hotel, for helping us make the 80th Los Alamos Old Days a celebration worthy of this milestone!
