Definitely depends
San Diego really requires some effort in finding the right provider. There are just so many from LA on down that you should really read some of the boards. Tijuana works for some but is not for everyone. Have had some friends who have had some successes and failures. Really depends on you. I, for one, just don't like the "go to the bar, check out the Chicas, negotiate, etc." even though I have done it a couple of times. But that's just me. For many the price is right.
Recently, a couple of "big names" in the biz just moved to South LA which is only about an hour from me/San Diego. If you are interested in any specific input as to who, what's here, etc., please feel free to email me at pardek7@yahoo.com
