World Famous Racetrack!
What more can I say about the World Famous Del Mar Thoroughbred Club that hasn't been said already?
This place is an institution, not just in SD, but in all of Southern California. Opening Day is one of the biggest days of the year in SD, and if you're lucky enough to get to go, one of the funnest as well.
But even going here on a random weekday is fun too. And the summer concert lineup can't be beat! They always cater to everyone's tastes, and they always have amazing groups come to play after the races.
And let's not forget that great BeerFest every year!
