oceanside isnt to far from sd, its actually consider he heroin capital of the world haha.
but your best bet is to hit la jolla or san diego for sure. hit up sea world or see a show at soma
Haha you need to come to New England, 'specially in Fall... but I've heard of Oceanside, and I hear it's gorgeous out that way... Can't really help you much though, since I live on the wrong coast :P
