New York is another. Ultra-high-density communities may not be common in the US -- but the ones that do are exist are, well, kinda' a big deal.

But -- oh, yeah! -- we were talking about city planning as relates to lower-income folks. And the thing is, even though you and I might consider it impossible to get to work, buy groceries, &c. in much of the country without a car, there are still people doing that by necessity. My brother-in-law used to take his bicycle on the bus and sleep on a bench until his shift started, because the bus routes he needed shut down long before his shift started. When city planning is done in a way that assumes everyone is going to have a car, what you get is people left behind by the system. If you're lucky, they can manage to hold down jobs anyhow -- if you aren't, you have more folks who need safety-net features much more expensive than public transportation.

Don't know why I want to feed the troll -- and explicitly not accepting the assertions I don't challenge here, but...

You talk about "traffic flow" -- but think about this for a minute. You're proposing to take a very high-population, dense chunk of city -- plugged into the rest of that city's transportation network -- and move it out into the middle of nowhere.

Have you looked at the level of car ownership in high-density areas recently -- particularly in lower-income high-density areas? How exactly do you expect folks to get to work or school when they're suddenly no longer in an area with transit access? (And without that, how do you expect folks to work, or go to school to improve their circumstances? Would you rather be buying the same number of heads worth of homeless shelter, and getting no tax base at all)?

Hell. I'm in the rich part (financial district) of downtown Chicago, and less than half my neighbors if that own cars if that; being in walking distance from work (and directly next to a stop for every single L line) is why people pay to live in the Loop. Owning a vehicle is expensive in a city -- heck, parking wherever you're going to is expensive in and of itself, as is having a place to park that vehicle at home (in my building, a parking spot costs about $30k to buy, or rents for upward of $200/mo). You can't take folks who can't afford decent housing unassisted, move them away from their jobs, and expect them all to be able to buy, maintain and fuel vehicles -- and park those vehicles near their jobs in the city -- when they were only barely making ends meet beforehand. It's insane.

All this talk of choppers lately inspired me to rent Blue Thunder from Netflix.

"a relatively small and affordable CNC milling machine that could easily manufacture the lower receiver of an AR-15"

How about:

"a relatively small and affordable CNC milling machine" STOP.

I love how media likes to paint something as evil if it can be remotely associated with the subject of their agenda.

It's a milling machine. Just like a hammer is a hammer.

I was at the Museum of Natural History in DC a few weeks ago and got hit in the face more than once with those stupid things. I complained to the curator's office before I left, and I'm glad I'm apparently not alone in doing so.

Nobody's going to run off with your camera. Just ask someone nearby to take a photo of you.

The batteries must be replaced or recharged:

1) When the transmitter has been in use for more than 1 cumulative hour; or

2) When 50 percent of their useful life (or for rechargeable batteries, 50 percent of their useful life or charge) has expired, as established by the transmitter manufacturer under its approval.

This has zero chance of becoming law.

Okay, good work. But in their model, do they make the assumption that everyone on the continent is trying to make for Glacier National Park? Because, now that they've told everyone that's what they should do, I think their model should account for that.

The legal theory is the delegation of powers. Congress delegated the power to write legislation within a certain scope, breadth, and depth, to the executive branch of government, authorizing it to set up an agency to manage same.

Congress has the right to delegate its power to legislate to other branches of government. It is unfortunate, but we are learning now that it has delegated pretty much all of its power.
