If you live in Grant Park, the Neighborhood Association wants to know if you've seen any black widow spiders around. Why? Because they're on a killing spree, and you could be next. Just kidding...black widows (aka latrodectus hesperus to those arachnophiles or Latin speakers out there) don't usually kill people unless they're really young, really old or infirm. But they can mess you up pretty bad, bringing on aches, nausea and making breathing difficult. In any case, if you live in Grant Park and have seen any of these, let them know.
