EBV is by far the best, however, there is also Great Valley Serpentarium which is a snake museum as well as a retail outlet for their breeding projects. GVB is in Lodi, CA, and I think they also have a website. I live up in Sacramento and sometimes we take a Saturday and go to both. They are about and hour to an hour and a half apart.
When will you be here? If it's soon then those two are the best. If you are coming after babies hatch there is another small store in Elk Grove that breeds cornsnakes. They won't have much though until May/June.
