Nevada Naturist, glad to see you'll be coming to Blacks Beach Memorial Day weekend. I've been going to Blacks for over 20 years. There have been some recent changes there that you should be aware of.
Nudity is no longer permitted on the San Diego City portion of the beach. This is the portion south of the dirt Gliderport path leading to the beach. Signs are posted.
Nudity is permissable anywhere north of the dirt Gliderport path.
As you recall, the beach still has informal areas of use. Singles and families use the beach below the Gliderport. Gays predominate on the northern portion.
Due to several recent landslides, please do not set up your stuff too close to the cliff. Someone recently was buried alive as they were laying right at the base of the cliff.
The usual etiquette applies - no photographing anyone without their permission, and no overt sexual activity. The rangers patrol and check for it -several people have been photographed and fined.
Hopefully, the "May Gray" will be gone and you'll have sun. Jerry and friends continue to sell beer and soda, and the nude volleyball action will be happening. Enjoy your visit. I'll be happy to answer any other questions.
