from the San Francisco Chronicle:
http://www.sfgate.com/cgi-bin/article.cgi?f=/c/a/2008/02/21/MNABV5PP3.DTL "At 20 miles a month, a determined Burmese python from Florida could arrive in San Francisco as early as August 2020."
"The snakes also like to eat rodents, deer and other mammals. Small Florida deer have been turning up inside the digestive tracts of Everglades pythons, which has alarmed deer lovers and also the deer."
"As for other potential prey, human beings - like rodents, beavers and deer - are mammals, government scientists confirmed."
and my favorite:
"There is nothing bad about snakes, the misunderstanding in a certain garden notwithstanding. Snakes are just being snakes. It's up to people to exercise their free will about snakes, which is the oldest lesson in the book."
