Grew up in Lawrence, several friends that live and work there, and my mom & brother still live in one of the neighboring towns that thankfully wasn't hit. I live on the MA border not far from the highway and could hear sirens all night from all the surrounding fire departments rushing down there. Scary stuff. It's bad enough as it is, but surprised and glad it wasn't a lot worse, in scope and casualties. I still can't imagine what the people that lost their homes and the family of the young man that was killed are dealing with.
Sorry your mom again, Dok. I'm hoping they can beat this one back too.
