The 37th running of the Marine Corps Marathon is Sunday in the Washington, D.C. area, and all the while Hurricane Sandy is making its way up the east coast. Marine Corporal Ben McCrosky from Camp Lejeune, North Carolina runs with a prosthetic on his left leg. He is ready for the rain, if it happens. After all, he’s a Marine. McCrosky is one of 30 combat wounded servicemen from the Achilles Freedom Team competing in the marathon or the 10K.
