It's usually a minor headache...but yesterday, everyone waited until the last minute to leave...it took us an hour just to get out of our parking garage...and about an additional hour to get home. On a normal day it would take about 15 minutes.
Columbus is big, but the OSU campus is actually pretty close to home. Especially if you know what streets are one-way and can get you out quickly. The campus police were getting weird about who could turn where last night.
