I used to live 3 blocks from the Hancock Center worked nearby the Sears Tower during my summer in Chicago...Chicago PD and the Feds are definitely closely monitoring those sites for suspicious activity, as security is tight around that area...and although it wouldnt surprise me if they're targeted, I still believe that the nation's highest level of concern for future attacks remain in NYC and Washington DC...but I wouldn't necessarily feel 100% safe in any major US or international b/c the world is just not the same anymore...

I was in Madrid just a few weeks before the bombings, and used to ride the train at the very same station where the largest explosion took place (Atocha)...future attacks are emminent, its not a matter of "if" but "when" ...I pray for peace in this world, and in the afterlife...

PS- wattup MaryJane!
