Where can I walk in and play basketball and other gym activities at the the university? Is there an athletic pass?

Everywhere I look there only seems to be rent out fees which are very expensive.

Walk into David Bradley Athletic Center anytime of day into any of the gyms and there's usually a game of pickup ball going on. Sometimes (rarely) its rented out and you can't play, but usually its open for everybody, so just jump on a team for runs.

***There's also 3 v 3 intramural (half court) and 5 v 5 intramurals (full court)
