Del Mar race track officials estimate about 100-hundred-million dollars will be generated for the county once the horse racing season is over.
That's the same figure as last year, but much less than in previous years.
Reports show economic benefits to San Diego county have significantly decreased since 2003.
Mike Ernst with the Del Mar Thoroughbred Club says attendance levels are on par with last year, but people are betting less.
Ernst: It's something that we've seen in trends at Las Vegas. You've seen that in the Indian gaming casinos locally that business has been off. We're pleased that people are still coming out to Del Mar at the high levels they have been in past years and we certainly understand that when times get rough, they're going to spend a little bit less.
Ernst blames the poor economy for reduced betting.
He says about 40-percent of people attending this season come from outside the county.
