The Rapid City Area Chamber of Commerce sold out its space Tuesday night for its annual Business to Business Expo at the Ramkota Hotel.
Seventy-seven businesses set up booths at the get-together, up a handful from past years.
A lot of them had games or other fun ways to attract an audience.
All sorts of businesses turned out, including banks, health care groups and a lot of small businesses from the area; all were Chamber members.
The Chamber expected roughly 600 people to come and explore the Expo, and although it cost between $15 and $21 a person, it's not really a fundraiser.
"It's really more about the awareness of the businesses to the community," said Karissa Eifert with the Chamber. "That's really our goal, more so than it is to raise money."
The Business to Business Expo is the Chamber's best-attended event throughout the year.
