Walking with Superman: Day 65

Austin, TX is home to the world's largest urban bat population. Usually this makes for an impressive sight at sundown, and the greatest dangers are rabies and falling guano, but something is turning Austinites into the world's largest Man-Bat population! Superman's in a race against time to find the cause--and the cure--before everyone in Texas sprouts leather wings. But will he succeed, or will the strange effect force Superman to convert the Fortress of Solitude into the Supercave?
