Here's a sign I saw whilst riding the #10 bus into work today: ELF DEFENSE. Now, I knew those guys could be trouble, but that this problem had grown to such proportion that we needed a planned, co-ordinated response was news to me. I pass along the information - and a reminder that perhaps nothing provides a better shield than some bread in your pockets (please see our Fall issue for more info).
