As tradition in years past with LAist, we visited the tri-annual UCLA Undie Run last month for the Spring Quarter midnight event just prior to graduation. To say the least, the party was massively huge. It took just under 20 minutes for the thousands of students to get through the Strathmore tunnel.

The event was so wild that LAist photographer Tom Andrews' camera came to near death in a water balloon fight (everything is okay now!), people were swinging from trees, the police put on their tactical/riot gear and there was a much more variety of happenings going on this time around. UCLA student Ryan D. Knight also helped out by contributing many of the wonderful crowd shots. And with that, finally, here's your Undie Run. See you next December.
