Here are a couple of strange databases I keep regarding my home state, North Carolina:
The North Carolina Black Triangle UFO Sighting Database:
This is a database showing reported sightings of triangular UFO’s: giant black triangles, boomerang-shaped, and “V” or “Chevron”-shaped craft.
The North Carolina Motel Meth Lab Registry:
Documenting operational methamphetamine labs found in North Carolina hotels and motels.
