How to Be Blindfolded on a Football Pitch

A football field is a 2D surface. You can only move in two directions. We're not going up or down. And it took three people before we knew where you were. It took one more person than the number of dimensions that you can move around in, like in a jetpack in the football stadium. With now, there's actually two places on the field, which are 10 meters from me and five meters from Lauren. That's the triangulation.
