Just found out about this right now. WTF is wrong with this world, when you can't even go for a fun run without the risk of being blown up? I haven't read the full thread yet, but does this have the smell of homegrown terrorism, do you think? Either way it's a despicable and cowardly act, and my thoughts, as I'm sure all of yours, are with those who were injured and their families, and of course the families of those who lost their lives. A black day.
