Here's my garage, at least what there is of it today. In the foreground you can see a short yellow stake in the gound, then straight above that about 40 feet distant is another stake just like it. That's the front side of the concrete slab that will be poured there. If you stand next to the nearest stake, make a 90 deg. turn, you'll see a third stake about 72 feet away, the line between the two is where the right edge of the slab will be.
As you can see, there's a few things to smooth out before we go much further with the project.
But, there it is, my super humongous garage. In the raw, so to speak.
