The Chicago Tionol is being held at DePaul University, located in the Music Mart building in Chicago's loop district. The Music Mart is located on the corner of State Street and Jackson Avenue, at 333 South State Street. A good general map can be found here, http://www.chicagomusicmart.com/Html/general.html
We are currently scheduled to be in the DePaul Conference Center on the 11th floor. As room assignments are acquired, we will post them here, so check back before the tionol for more details!
