After an unusually warm winter and an even warmer start to spring, rattlesnakes are on the Front Range due to increased temperatures. Dr. Kevin Fitzgerald, a veterinarian in Colorado for over 40 years, has been monitoring over 500 rattlesneaks on the state's eastern Front Range for over a decade. He advised people to give the snakes plenty of space and not to try to move them. If someone is bitten, they should immediately seek medical attention.
