Ruby - totally agree on the hot dog topic, obviously. If you haven't had a real Chicago dog, then you're missing out on one of life's better foods. I always liked the little hole-in-the-wall joints for Chicago dogs, I used to go downtown near Adams & Wabash for lunch every so often and get a polish with everything. No clue on the name of the place. Also, Duks near Western & Chicago Ave is awesome. They deep fry everything, including the hot dogs. And the bacon. Yes, you heard me.
It's probably 75-78 degrees here today. Like every day. The lake is smooth as glass from dawn until about noon, but winds come out of the Southwest in the afternoons and make it rougher. Water's just fine - cold out in the deep, but near shore it's just right for a dip.
