Some pranksters got into the controls of this road sign and left a funny message. I wish I saw it the evening I was traveling home on I-35 from Waterloo Records but according to a more detailed story, (caution, there is a video segment from a local pair of TV news zombies) it happened sometime between Sunday night and Monday morning; I went through the intersection on Tuesday evening.
A big round of applause for Austin’s police department for not overreacting unlike Boston’s finest two years ago.
