If you're not from here and want to spend some time outdoors, the lake is a great option.
It's south of the venue. If you head south on Broad, turn east (right) on Broadway Ave, you'll end up taking the road that circles the lake! Park somewhere for free and take a walk around :)

Hungry and don't know where to go? This restaurant is one of the Becker family faves. It's fairly close to the event, just south on Broad street. Awesome food, good service! Kid friendly.
