Cloud Gate or The Bean as it is affectionatley referred to by Chicagoans.
One of the reasons I chose the bike I did are sites like klr650.net and advrider.com which are tremendous resources not only for customization and maintenance, but also for trip planning. I needed to change my oil while in Chicago, but I didn't have a place to do it or a way to dispose of the used oil. I posted a message on these forums looking for a venue and was invited over to a fellow KLR rider's house where I got the job done. Thanks Jon!
