Mixed among the fans of teams that made it to the Final Four is a noticeable contingent of those representing others, like Gonzaga, Purdue, Oklahoma State, Virginia and Evansville, to name a few.

Among the blue-and-maize crowds of Michigan fans on the Riverwalk near their team hotel were the Fosters of Tucson, Ariz. The retired sports bar owners were decked out head to toe in University of Arizona garb and were repeatedly posing for selfies with fans of other teams. Freddie Foster wore a hat that had basketbal net on the top, while her huband, Jamie, sported a necklace with basketball beads about the size of baseballs.

"We're hear to talk smack even though our team isn't in it," explained Jamie Foster, who is attending his 30th straight Final Four with his wife. "We wouldn't miss it for the world. San Antonio is one of the greatest places for this."

Stacey Steger of Falls Church, Va., stood out among some Kansas fans. She was wearing a Duke t-shirt and cap, while her husband, Steve, a graduate of KU was wearing Jayhawks apparel.. Kansas beat Duke in overtime in the Midwest Regional final to make it to San Antonio.

"I'm getting a lot of stares," Stacey laughed. 

"We knew one of our teams were going to be here so made our reservations earlier than most," Steve said.

The couple's son is a senior at Duke and their daughter is a freshman. 

"My kids told me that I better wear Duke regalia and represent," said Stacey, a civil servant with the Department of State. "But I can't believe I took off work to go to a Kansas game."
