Borrow pit? Thats a new one for me

Right across from my barn is the county park and bulk dump, which has this HUGE hill from where they dug it out, with nice smooth footing. They also have 50 acres or so of riding and hiking trails. There used to be a big gate blocking it off so that you couldn't leave the trail and get to the hill, but someone took it down and we have had some fun going up and down it.

If you ever make it down this way I'll take you its right across from my barn so we just saddle up there, cross the road and go.
