It may not look like it, but this is a shortcut. Or at least it will be when it's finished. It's a shortcut to the owner's guest house. Halfway down the trail there is a bank of shared solar panels. There's also a storage shed for shared tools. It also doubles as a running trail. The houses are two miles apart. Both are on the sides of small mountains. You can see the other house from the porch of the other. The owner planned it this way when he bought the property. That was 3 years ago. The houses are already done. If implemented correctly, the other things will fall in place.
It's the same way with URL shortlink services. Planning a little will go a long way.
