Zippy: I can certainly relate to wanting to become a race caller, as I had that desire shortly after I was introduced to the sport at Ak-Sar-Ben racetrack in Omaha, Nebraska in the late 1970's. I started calling races into a tape recorder on the roof at Turf Paradise in the early 1980's and the late Bob Weems of Turf Paradise, Monmouth Park and Atlantic City Racecourse became a mentor to me, even encouraging me to "stay after" the guys on The Arizona Fair circuit until I finally got my shot. The rest as they say "Is history"
Although I haven't met Sam, I'm sure many race callers today have a similar story, as I certainly know a few that do............
