Giant tents are going up all over Tucson in preparation for the Gem, Mineral, and Fossil Showcase that kicks off in less than two weeks. The tent city shown to the right is across the road from the AZGS offices and the federal court building is visible in the right rear.
Tents are filling empty lots, while entire motels are being converted into bazaars. A guide to the 46 or so shows contains maps and shuttle routes.
