These two are wonderful, and you have many nice ones on Flickr. The first one here is outstanding for the clouds. Nice idea to shoot through that "grid" on number two.
It really is an interesting city; we go there fairly often to see our daughter. If any of you visit, I highly recommend the architectural boat tour. (Take it on a cooler day. There are several operators and I have no idea which is the best. We've been on two and they were both excellent.) Thanks for your comments. I appreciate them!
I'm late but catching up on unread posts-- just want to say that the first Chicago photo is really fine. The foreground fountains bring in a sense of exciting things happening.
