I am looking for some unique and interesting wedding shots to put on my must have list.?

We are having our ceremony on the cobblestone bridge overlooking the south pond at Lincoln park Zoo with the city skyline as a backdrop (weather permitting) in September 2008. I love anything and everything chicago. If you have a gritty or pretty city seclusion please let me know. I don't want typical I want cherished and fresh even for my great grandkids 100 yrs from now. thanks for the thoughts.. Amanda
