Road Cycling It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle. -- Ernest Hemingway

Informative but predictable. Good info.

The first two I might try but grass? No way, I'd rather walk all night to get home.

Predictable? You predicted cutting it in half and tying two ends?

If the knots leak over a long distance and if your life is at risk, I would consider filling the tire with dirt/sand if no grass is around.
It would be extremely heavy, guessing 5 kilos, but the tire would hold its shape.
You would have to ride slow since it would steer dangerously but better than walking a long distance through bear country or South LA at night

My real world solution one time was to find some plastic bag litter and wrap it around the hole 5-6 times as a patch. It held air for a week, then I remembered about it and fixed the tube.

I've heard of the grass thing, but not tying the tube like that. Good idea to keep in mind. Hope I never have to use it.

No, I predicted the one knot in the first example. I didn't see why on knot wouldn't have sifficed for the second example also. I felt cutting the tire and using two knots was just sensationalism. It has to be really hard to get the tube to fill the tire when it is not continuous around the circle.

Because the hole was wide, so you'd have to pull through too much into the know which would over stretch the remaining rubber and likely lead to a new tear/flat.

Yep. I know what he was saying, but it doesn't look to me like two knots helps a whole lot. You still have to eliminate the full width of the hole, and two knots has to take up more rubber than one. Unless he doesn't make the ends of the tube meet and leaves a flat spot where there is no tube. I would rather take my chances with the one knot.
