Sometimes we'll skip the Encanto or F.Q. Story home tours, but we never miss the Willo neighborhood tour, which usually falls on a weekend in February each year. Willo — bounded by Central and Seventh avenues and McDowell and Thomas roads — is one of the largest historic neighborhoods in Phoenix, with nearly 700 homes built between the 1920s and the 1940s. For us, it's like a holiday to wander through Willo's wide variety of architectural styles — 1920s bungalows, 1930s Spanish Colonial Revival, Tudor Revival, Greek Revival, American Colonial Revival, and Pueblo Revival homes. We even like the mid-century ranch houses. And after we've wandered through a dozen or so cool old houses, checking out the rehabbed kitchens and the neatly period-correct moldings and doorframes, we like to grab a quick bite and do a little shopping at the Willo street festival that's one of the best parts of this fun-filled event.
