I live in Florida and I don't travel up North very often. This summer, my family is having our reunion in Chicago, the second week of July. Should I take a sweater and a pair of long pants in case the weather gets chilly? Does it get chilly when it rains in the summer or is it hot. I usually wear capri pants but I hate being cold, so I just wanted to check with folks that live in the windy city. Thanks for your help with my problem.
