Please familiarize yourself with the map before leaving for a meeting and leave extra time for navigation. The address is 2520 55th Street and the building is adjacent to 55th Street, near the Daily Camera building.
January through April meetings will be held at the Boulder Rural Fire Protection building at 6230 Lookout Road. This is the same location as previous years. Please note that the entrance is off Lookout Road, not 63rd Street.

All winter meetings are held on the second Tuesday of each month and start promptly at 7 pm and last until about 8:30 pm. Book sales will be present, so come early to shop!
