--Apple-Mail-6--1060886000 Content-Transfer-Encoding: 7bit Content-Type: text/plain; charset=US-ASCII; delsp=yes; format=flowed I'm guessing that Peter Stow's squids at Hubbards are Shortfin or Boreal Squids, Illex illecebrosus, which is the same squid as the ones in the "Squid Jigging Ground" song from Newfoundland?
