Icelandair holds The Last Bostonian Skating at the Community Ice Skating @ Kendall Square rink in Cambridge on March 5 to raise money for the Special Children Travel Fund and Children’s Hospital Boston. Five teams will compete in a series of airline-themed challenges that test endurance, speed, showmanship, and creativity, in a quest to win a trip to Iceland. They will race to see who can pack their luggage and deliver it to a flight attendant the fastest — on ice. Meanwhile, you and your friends get free admission and skate rentals (based on availability), and will be treated to family-friendly Icelandic music and entertainment. Donations welcome. The competition runs noon-3 p.m., but the rink is open to the public 11 a.m.-9 p.m.
