Couldn't leave it in Chicago...wasn't near enough to a cache big enough to hold it. Dipped it here, near the Lincoln Park Zoo. Took a pic of it on the Lincoln Park Zoo sign (along with other TBs) and took a pic of it on the 99th floor of the Sears Tower from earlier that day. It was a chilly, rainy, windy day...but he enjoyed the sight seeing all the same.
