Stretching along 22nd Street from downtown all the way to Harrison Road, then turning south toward Golf Links Road, route No. 7 offers a real slice of Tucson life. Riders range from smartly dressed business people to rambunctious school kids, the homeless to mothers with babies in strollers. Like those who rode Tucson's trolley back in the 1920s, these passengers are a reflection of the diversity which make up our community. Plus, the route goes by some of our favorite places in town, including Reid Park and the Columbus Public Library. So, if you're looking for somewhere to go, why not plunk down a dollar and take the bus to the zoo? The animals will love it if you do.
