What to do i n Chicago?

Tonight I will be in Chicago (Chi-town really?)....I'm only going for about 56hours....for my cousin's bachelorette party.

Now her idea of plans for the weekend consists of shopping, eating (smancy pants eating) and drinking.

As a result of a very 'grown up' Tuesday this week... I'm more interested in how much I can do for free.

Like going to see that silver jelly bean thingy (Cloud Gate?).

National Geographic has some free ideas.

But if you've got any excellent ideas for me, please let me know! Otherwise enjoy your long weekends!
