That also includes house parties around Stillwater," said ABLE Commission Captain Erik Smoot.

You can park downtown for free in the 500-plus free parking spots Thursday afternoon. Then three hours before the game a shuttle service starts. It picks up at 7th and Lewis and runs every 15 minutes before and after the game.
