THE PAGAN'S Motorcycle Club didn't burn down the boardwalk during a biker rally in Wildwood last weekend, but they did take a few moments to plan a thoughtful Christmas gift for some fellow bikers. Unfortunately, "Christmas presents" was a phrase the outlaw motorcycle gang used for homemade hand grenades, federal officials said, adding that some Pagans in Wildwood last weekend were plotting to use them to kill members of the Hells Angels, their biggest rival.
