sacrenter, i remember el morro fairly well. there used to be several of these trailer parks along pch back in the day. think of mel gibsons home in the lethal weapon movies (filmed at el morro beach, i believe.) over time this highly desirable beach front property has been slowly converted into more profitable uses if on private land. the montage resort in laguna beach sits land once occupied by the treasure island rv park. and in the example of el morro and crystal cove, the land is state-owned and recently converted into camp grounds.
residents fought the conversions tooth and nail, usually trotting out in front of the media some old lady who lived in one of the trailers her entire life and was now getting displaced. of course most of these trailers were owned by wealthy families who basically had ultra-cheap beach front vacation homes.
when land under san clemente's palm beach rv park was recently put up for sale, the residents initially cried foul. "oh no, how can you kick out us po' trailer folk from our homes?!?!" fortunately the lease obtained by the park residents in the early 90s granted them first right of refusal. so the forster family, the original ranch owners of what is now san clemente, said ONE MILLION BUCKS each and you can stay in your trailers. most of the residents coughed up. po' trailer folk indeed.
