Are there any internships or college programs for high school students that are still accepting applications?

I'm going to be a senior next year and just ran out of time. This is my last summer to get an internship or participate in any type or leadership opportunity before college application deadlines in November, but most applications for internships are closed. Are there any still open? Hopefully in or around San Diego and not involving science.I would even be willing to do a fall internship or program. Does not have to be paid.
