Too Many Margaritas?

Maybe someone had too many margaritas at the Border Cafe in Burlington today? I hope not...

I don't really know what happened, but when I was driving home from work today around 6pm the light on the Middlesex Turnpike was all backed up because a firetruck, several police cars, and two tow trucks were blocking the right lane and the road to the right going in/out of the Border. There were no ambulances by the time I got there, but I didn't see any people other than police/fire - so my guess was the occupants of the vehicles were already taken away. Both cars were getting hooked up to tow trucks and being taken away as I finally got to pass the whole mess..

Anyone know what happened?
