Aunt Heather is coming!

Yeah--Aunt Heather gets to visit for the weekend! The kids (and I) are very excited. Heather usually comes in to watch the kids or do some work training, but this time she's coming for fun (well, and a half-marathon with me). She has not seen enough of Chicago for all the times she has been here. What to do...the architecture tour, Art Institute, Navy Pier, Michigan Avenue, Botanical Gardens, Sears Tower, Shedd Aquarium, Adler Planetarium--the one that's supposed to get the $3 million dollar "projector" you've been hearing about, any one of the 3 zoos... (no baseball anymore so that's out)..there's so much to do here and just not enough time!
