for anyone who may want to do more research and reading about tigers- this is a great little site that a guy in Maryland started a couple years ago-

http://www.toothycritters.com/

there is alot of info that relates ONLY to tigers (most sites focus on pure strain and there are a lot of differences)

AND I am planning to get the year-long license for mass this season and do some trips up to Pontoosuc in Pittsfield, MA- would love to have a couple people meet me up there when I go - we did a couple days there last November and it is a GORGEOUS lake- we caught a few nice pike - but no sign of any tigers- but they are in there and have been for over 10 years- 40 inch plus fish for sure
