Great railroad picture. Thanks Massu.
Tysons Corner, not Vienna.
This picture is not Union Station in Washington, DC. It's actually Grand Central Terminal in New York City.
That bridge is not on or crossing private land, it is crossing a public waterway. There is plenty of precedent. If you let your yard grass grow too high the county will mow it and bill you. In many jurisdictions, not just HOAs, an eyesore house or building will accumulate violations and fines. Same principle.
Featured in the 1991 movie Liebestraum.
First time I passed it I said what? The windmill does spin and turn like the real working ones. I'm pretty sure from what I've heard, it really was a working windmill before it ever was a cell tower. You are right its purely ornamental on the cell tower.
This building was a chemical company at least into the late 1980s. The building predates I-287.
It's the entrance to Camp Gaw mountain reservation. The deep cut of the highway eliminates noise and you can't even see the highway it from the ski slopes, either.
Most of this was not wooded, but was an overflow parking for Metro until the massive parking garage across the road was built. WMATA had owned this land for many years in the hope of high-density development around the station. This is now happening.
Most of this forested area was already cleared in the late 1800s and early 1900s. What you see growing here is second and third growth from previous clearing.
The use of this land for high-density growth is a great development, so-to-speak.
