UFO and Paranormal Road Trip This Summer

I want to take an UFO and Paranormal Road Trip this summer. I live in Southern California and I think it would be a lot of fun to visit the actual sites. I was thinking maybe Area 51, haunted cemeteries, ghost towns, festivals, haunted houses, Hollywood Roosevelt, Roswell Crash Site, Joshua Tree, and any location that has been abandoned for 50+ years. Any suggestions?
