Even though it's green, trail D is one of my favorites. Just because of the amount of water holes in it.
Any time I 'm leading a group of smaller rigs/stockers, I run them heading towards the pole line. When I hit the "entrance", I hit it pretty hard to push as much water out that I can. Going the opposite way tries to push the water uphill and runs right back down in it. Leading a group of bigger rigs, I'll lolly-gag thru it just to leave it deep ;O}
