This free model train show, displaying Christmas scenes in various model train gauges, has been a local hit for many years. Enjoyed by kids and adults alike. As in years past, the organizers will be taking donations of canned goods, toys, new clothes or new blankets to SERVE. Santa will appear on Friday and Saturday.
