P.S if your country doesn’t have the freedom to roam https://en.wikipedia.org/wiki/Freedom/_to/_roam there’s something inherently wrong.

The way I learned it is that T looks like a hanging stalagTite and M looks like two jutting stalagMites.
Yeah M is spikes sticking up from the ground. T is a spike hanging from the ceiling.
