Here's a link to a very good article on Frank Mirahmadi, who will be the regular race caller for the upcoming (only 2 days away!!) Saratoga meet.
I remember when Frank was race caller at Hialeah and for several races every day he would do an impression of some other well known caller. Some of them were very funny. As he has moved to higher profile tracks, he has toned down his act and his calls are very professional.
