Northwestern University is located in Evanston just north of Chicago.
The meetings will take place in the Technological Institute ("TECH"):
2145 Sheridan Rd., Evanston, IL. 60208
This (very large) building is 0.7 miles from the Orrington Hotel.
The drive from Fermilab takes between 1 and 1.5 hours, depending on traffic.
Parking is available in two parking garages for $8/day. Street parking is difficult and not recommended. More detailed information about the parking garages is available here. The North Parking Lot is closer to TECH. Here is a map:
Instructions for getting from the North Parking Garage into the TECH building are available on the Meeting Location: Rooms page.
