The Radar: Chicago Architecture Tours, Spring Skiing, Best Small Airlines

• The Chicago Architecture Foundation is adding new tours this spring, rounding out its growing roster to a total of 85 city tours. Try the new Vice to Nice tour, a look at the transformation of Chicago’s South Loop where the buildings reveal stories of colorful politicians and reformers. Or try the Synagogues By Bus tour, modeled after the popular Churches By Bus tour, which explores Jewish history, traditions, and architecture. [CAF]

• Don’t pack up that snow gear just yet. Our friends over at Matador present their guide to the best places in North America to ride some powder this spring. [Matador]
