It seems like something out of an episode of Are You Afraid of the Dark (90s kids, you know what I'm talking about…), an abandoned running track in the basement of the former Juneau High School.
And that's where OnMilwaukee's Bobby Tanzilo takes us this week for Urban Spelunking.
The track was used for student practice and track meets in the 1930s and 40s, but it's unclear when it officially closed.
Remnants from its past are still posted today, including hand-painted student records on the walls and collapsed wooden bleachers (pictured above).
How did Bobby find out about the "secret" track? What was the weirdest thing he saw down there? Click the podcast player above the photos to find out.
