Talk to folks who’ve been around racing for a while, and one thing becomes clear: it doesn’t take much to get them talking about horses from their past.  In today’s Midweek Movie, Jeff Krulik catches up with Linda Bernier, who’s worked on the backside and whose husband, Lou, is assistant trainer for Ferris Allen.  In a flash, she has that faraway look in her eyes as she’s remembering horses like General Assembly, Hay Patcher, and Root Boy.
