This is odd. Seems strange to set off explosions late into the race. I wonder if security becomes more relaxed after the winners get done and the nut jobs took advantage.
Prayers go out to the wounded and killed. Very sad day.
A friend of a friend was running out there. I saw a fb post this morning reminding everybody to root for him. Hopefully he was out of the area. Per his bib # and tracking info, he should have been.
