What is the structure, and what purpose does the light (flare?) serve A: Looks like a factory where whatever they make also produces a flammable gas a by product. They just seem to burn it off instead of letting it build up to dangerous levels

What is this thing? Found it as a kid and have never known what it is. Slightly heavier than it looks. Says US 4 inch on one side that also has an “L” in a diamond, the other side has some mark I can’t make out. The triangle is 4 inches from base to tip. A: I believe this is an “earth anchor” sometimes called an “arrow head anchor”. The part that sticks up opposite the point fits into a shaft and it gets driven into the ground. There’s usually a steel cable that gets routed through the holes.

Why does this mailbox of letters around it? Building was built in the early 1900s A: It used to be a combination lock. Now retrofitted with a key lock.

Hello, they erected this thing in the center of a neighborhood, its blocked off by a green tarp wall on each side. A: This is a drilling rig. Fracing is a separate process. Anywho… I looked on the FL Oil and Gas Map and it only shows one well in Broward County and it looks like the permit was terminated in 2017. I don’t see any permits pending on Broward County.

Solid paper-plate-looking cover on wall - from bedroom in house built in the 1950s in SE United States. A: It’s a cover plate for a stove or fireplace pipe.

Spotted in a public restroom. Middle part rolls freely. Any ideas? A: There used to be a rubber roller around the middle piece. These usually get solved as a door-stop and/or purse hook.

Metal part, found in my driveway, doesn’t spin. A: It’s a fitting that attaches to a irrigation line . Then you blow water out of the line with a air hose to get it ready for winter (blowing out the sprinklers). This is the same kind of stem that is on your car tires.
