There are still too many photos to post from my adventure in the South Side Slopes, but here are a few more. From a quick google search, I'm pretty sure this was at the South Side Park. The Getting Outdoors Website says it's:
reached from Quarry Street (18th Street to St. Patrick to Quarry). The park features 65 acres of ballfields, walking trails, a playground, and a former ice arena. South Side Local Development Company and South Side Slopes Neighborhood Association recently convened a task force to plan park improvements.
