Finding disc golf courses - one near Yosemite?

[Tim]

Hi,
Going to Yosemite for a week or so, anyone know of any good course somewhere between SF and Yosemite?  I'll keep looking around but if you know one let me know.

Speaking of, why doesn't anyone have a site that lets you search for disc golf courses using a map instead of having to know a city name or zip code...  (or is there one?)  

I'm sure there's at least 100 cities between here and Yosemite but I don't know the names of them...   Or even by county might be easier...  

Thanks.

Just realized the pdga directory finds the nearest course if you enter a zip code so I'm all set...
