Two Mainers who were killed in the line of military duty are among the men and women who will be honored by NASCAR over Memorial Day weekend. The names of Gary Ivan Gordon of Lincoln, who died in 1993 in Somalia, and Kyle Milliken of Falmouth, who was killed in 2017 in Somalia, will appear on the windshield of Monster Energy NASCAR Cup Series cars during Sunday’s Coca-Cola 600 at Charlotte Motor Speedway. The race will be televised at 6 p.m.
