I've completely cleared the ravine and started on terracing it.
I had a lot of brush and small trees to cut down.
I apparently cut one of the little trees at a sharp angle leaving it as a sort of "spear" jutting out of the ground.
Most of the brush was dried but had big clusters of round prickly burrs.
I was trying to weave in and under this stuff, cutting the branches without the burrs sticking to me and as I did this, I stepped on the "spear".
Luckily I had my thick old gardening Crocs on and the sole took much of it.
But still, it hurt and there was blood.
I figured I better go clean it out and bandage it up and as I was hobbled past my patio area and I suddenly realized that "dog" is not the proper word for my level of exertion!
