Dear tPfers in Chicago! I have posted a thread about a month ago about a Chicago trip and you guys helped me so much, I thought it was way better than any travel guide book! Most of you who answered me said pack a lot of warm clothes....'cause it's super cold and windy(especially when I am coming from Sunny San Diego!) but I was wondering if the weather is still that way or got warmer...'cause San Diego got so much warmer in last month or so, it feels like beginning of summer, I see so many people in their tank tops at the mall! So I figure, it must be colder there, but warmer than a month ago? Should I bring my boots and winter coats? Help needed! Thanks~!
