gravel

The roads are gravel at best, and often just packed dirt or sand. You can very easily get bogged, if you don't know what you are doing.

If you suck at it you are selling polished gravel. The quality of the rocks doesn't matter.

Uphill both ways, in the snow, on a breakfast of gravel and no documentation. Total downtime, maybe half an hour.

I paid for it working as an "auger boy" on a gravel drilling rig for a concrete company for five years. I failed college algebra twice.

I just thought it was noteworthy that there's a middle-ground between green painted gravel like Sun City, AZ, and golf-course lawns.

I have no idea if Nissan found a way to make a cost effective, self cleansing film coating that can stand the test of gravel, acid, and time. If they succeeded, then it is a true accomplishment.

On inline skates I can plow through grass, gravel, potholes, anything, by shifting my weight back as I go over it. If something in the road catches you by surprise that's another story.

Tl;dr: Occam’s Razor demands the simplest explanation and so it probably was a stowaway piece of gravel

Anyone who skated as a teenager will remember being thrown to the ground by a small piece of gravel stopping the wheel. Add 2000w of tractive power and city traffic and you've got a recipe for disaster.

They both then proceeded to beat the shit out of me on the gravel parking lot ground. Now, I avoid going into the "hipster" neighborhoods of DC. As my wife pointed out, nobody in these neighborhoods is a helper.

My spectacularly mistimed 2nd attempt saw the wheel hit the curb full on, so I flew head over heels and shredded one knee to bits on gravel. Turns out you can keep biking just fine with a bloody knee, it only starts to hurt once the blood gets a chance to congeal.

The innocent sound of cars driving slowly on gravel, the popping sound of the rocks under the tires, made me hunt for cover from incoming gunfire for example. I was supremely agitated and on edge for maybe a good year after I got back.

What's more: "The site was deliberately backfilled sometime after 8000 BCE: the buildings were buried under debris, mostly flint gravel, stone tools, and animal bones that must have been imported from elsewhere." The reason for filling it up, which probably took enormous resources at the time, is unknown.

We're never going to run out of oil, just like we're never going to run out of gold or silicon or gravel or any other mineral resource. But as supply eventually declines the price may rise enough that petroleum can no longer feasibly be used as a vehicle fuel or chemical manufacturing feed stock.

Here in Europe a driveway is one or two car lengths of gravel or paving blocks. In the US, everyone's driveway is more like something approaching a major civil engineering undertaking, being the size of a tennis court, consuming several cubic metres of concrete, steel reinforcing, etc.

But pure supply and demand only applies in cases of perfect competition, where commodity goods are actually perfect substitutes; I have no particular reason to buy oil/ gravel/ corn from supplier X if supplier Y can deliver identical goods at a lower price. This is not the case for creative works.

Sounds like a system very slow to change,\nnearly self-perpetuating,\nlike more of an echo chamber,\nlike stew without garlic or pepper,\nlike ignoring that a stream bed is\ncold and uncomfortable, full of\nmud and gravel, but also one of the\nbest places to look for gold. Fundamentally the high karma people\npleased the masses at HN and/or\nhave been commenting at HN for a long time \nand maybe have made the better comments\nbut still are in the middle\nof the road.
