What does a two-fer cost the taxpayers of Massachusetts? A two-fer in this case is one rattlesnake and one eagle. An eagle snatched a rattlesnake and bites rattlesnake in half, rattlesnake bites eagle during attack, both die. Due to lack of transparency and accountability in DCR I’ll take a guess a million dollars for eagle, and two million for rattlesnake (snake bureaucracy much larger). That is a 3million two-fer.
