By BILL FINLEY It is horse racing, but not horse racing as you know it. These are the hunt meets, where they run steeplechase races, not at large sprawling traditional racetracks but in quaint country settings at race courses that oper- ate only a few days a year. There is no glass or steel or concrete and, most certainly, no slot machines, to be found anywhere. Most don’t even have bet- ting and most patrons don’t know an exacta box from a box of exacto knives. Only a handful have anything resembling a grandstand.
