What's the best way to get navigate the city during Open House Chicago?

Divvy, Chicago's bike-sharing system, and CTA buses and trains are great modes of transit during OHC. CTA and Divvy work well when used together—take CTA from one community to another then hop on a Divvy bike to navigate from one building to the next. Many sites are also within walking distance of one another. For sites not located along CTA routes, Metra train service is available. Some OHC neighborhoods have free or metered street parking.

What is a priority-access pass and who gets to go in the priority line?

OHC volunteers, CAF members, and OHC sponsors/VIPs will receive priority access to all sites. When enough people start to gather at a site—creating the need for lines—two lines will be formed: one for the general public and another, shorter line for volunteers, members and sponsors. To get a priority-access pass, become a CAF Member or volunteer for OHC.
