April and October: Cyclovia Tucson! This fabulous twice-yearly event varies just when it will be held but for the most part, it seems to happen in April and October. This is one hard-working group and one aspect of what they try to accomplish is shutting down our traffic and congested streets and using them for non-motorized traffic (mostly bicycles) and pedestrians. Their route is different each time and it creates a pedestrian mall all along the way with all kinds of assorted organizations demonstrating their information, plus food trucks and performers and on and on! Can't give these guys enough kudos! Enjoy the day!
