It must take an hour to get out of there.
I walk for 15 minute or run for 5 and I zoom up University and straight to I-15 with minimal slowdown.
Last Thursday night, I exited I-15 at 90th south at about 11:20 and heard on the radio that there was still heavy traffic trying to enter the freeway in Utah county.
I never leave a game until after the final play and I almost never get stuck in heavy traffic because I walk past it.
