Joomla Day Chicago is this weekend and this year we've been celebrating each Joomla Day by featuring a local Joomla site. For Chicago, we have the highest point in the city.
Sears Tower (recently renamed to Willis Tower) is the most famous landmark in Chicago. 103 stories up, at the top of the tower, you'll find the Sky Deck with wonderful views all across Chicago. Their website at http://www.theskydeck.com runs on Joomla.
Have fun if you're going to Joomla Day Chicago on Saturday and Sunday!
