This was the big mystery for anyone who was out in Old Town Fort Collins on Saturday night. Police crews had College Ave. blocked off from Olive St. to Mountain Ave., as two fire engines responded to a call from The Crown Pub.

A girlfriend and I were out on Saturday night, trying to figure out what was going on as we passed, and you know, assumed there was a fire. We hit up Trail Head, where apparently 'most of The Crown Pub' had gone to following the evacuation, according to a Trail Head Tavern staff member.

The surrounding apartments were also evacuated -- and let me tell you, it was about ten degrees out, so not a great night for those residents.
