And thieves, beware: As a security measure, the new porcupines at the Portland International Jetport are firmly affixed to a large granite slab. A woman from nearby Pownal donated the new porcupines to replace a statute reported missing in April. The only clues left by thieves were some broken quills and a hunk of rusty steel.
