This is a wacky place that's been in El Cajon for years. It's basically a church for people interested in science. They have some odd events during the year that involves people dressing up in strange costumes and doing weird things to their vehicles. Whenever they have an event the news media covers the story and you see all the interesting goings on.
It's not my thing but it must be to some people because it's been in existence in the same lcoation for at least 30 years. It's in an alright part of town and they do sell books, dvds, tapes, etc.
