Was digging around the -900 ft plane transponder location, some interesting things.

There's an empty lot nearby, google shows no address, duckduckgo however comes back with 333 Loma Metisse Rd. In the google maps image, it's clear that someone has driven over every square foot of the property… sweeping?

What's up with the negative altitude planes? Is that AGL or ASL?
