James Geist has spotted pythons twice within days in his West Milford yard.
Geist was reading on his deck when he thought he saw a branch move on July 23. He soon realized it was a snake.
Police arrived with two snake handlers who told Geist the branch was a 15-foot albino python.
Geist tells The Record newspaper the snake was huge, thick and docile.
Four days later, Geist saw another snake. This time it was a 10-foot python.
Animal control believes the tropical snakes were released by someone who had moved from the neighborhood.
