You know what I like about this photo the most? It does NOT look like an HDR. One small, very minor, issue I see is a little bit of crop on the left side might be in order. It looks like maybe part of another exhibit. That is the only problem I see with it. Great work.
You being from the windy city will probably understand this better than some: I was a truck driver back then, living in north west Indiana. I was on my way in to Chicago listening to Mancow like I did every morning. One of the first things he said when he signed on was that he was going to pull a prank on the people that tuned in late and when he did he wanted people to call in and back him up on it. When he made the announcement that the first plane had hit, I thought for sure that was his prank, and remember thinking it was pretty tasteless even for him (no small feat). That was the only time I remember in more years than I care to count that the C.B. radio was silent driving through downtown.
