I was watching the race when it happened but I didn't see any explosions... I'm in my dorm now and safe but I live basically in Kenmore Square which is where they say to stay away from...
Al my friends and family from home are texting me making sure I'm okay and a friend of mine that was at the finish line actually saw it go down and saw blood apparently and the police told him to run.
This is so surreal.

basically right in my own backyard.
