Langlotz and his crew are already setting up 132 tables and decorating them with maroon pleated-cloth skirts, unloading boxes of ribbons and rosettes, and organizing a "rot patrol" that will check entries each day after they've been judged to remove any food that is past its prime.
"When Bill takes something on, he gives it 110 percent," said Max Mosner, state fair general manager since 1972. "He is very, very organized and he loves what he's doing."
Langlotz grew up in Glen Arm and helped with his family's vegetable garden. He tried Cub Scouts and Boy Scouts, but said it was the 4-H Club that grabbed his attention.
"That was the big thing back then. Everybody was in 4-H," he said.
He joined the Glen Arm Boys 4-H Club, where his interests were vegetables and tractors. As a youngster, he entered his vegetables at the state fair many times, but didn't win many ribbons, he said.
He met his future wife, Ruth Ann Liebno, at a 4-H Club meeting in Rockdale in1966.
A year later, the Baltimore County 4-H Fair incorporated and he became its first president.
He and Ruth Ann married in 1969 and moved to Monkton, where their daughter, Laura, was born in 1976. The family raised sheep and Laura showed sheep at county and state fairs.
Today, Laura and her husband, Hans Kefauver, have a flock of 27 sheep in Hagerstown where they live, although they do not show them.
Ruth Ann Langlotz loves to bake and sew and has frequently entered the state fair competition. Last year, her jellyroll cake, pound cake and German bundt cake all earned blue ribbons.
She, too, works at the fair. This will be her fourth year accepting entries at the Home Arts building.
When Bill Langlotz retired from AAI in Cockeysville in 2000 after 40 years, he found more time to devote to both 4-H activities and the state fair.
His dedication was recognized in 2008 when the Maryland Association of Agricultural Fairs and Shows named him "Fair Person of the Year." He is now that group's vice president and will become president in November.
Although Langlotz gets paid for his fair work, he manages the farmers market for free.
"I want to be at the fair as long as I'm able to," he said. "I can't even imagine my life without the 4-H Fair and the state fair."
