wow thats alot of diggin, good work guys. if i were in the area i might break in my new SOS shovel.
6 foot trench eh, how about a couple turbo Apex's make a trench for the horses lol. I live on a ranch with my mom owning 15 horses, i'm not a horse lover by any means but i do understand how you guys feel.
hows the forecast look up there? i was just thinking a nasty 4 foot dump of fresh would really put a damper on your diggin.
really if a groomer could get anywhere close, putting them to sleep and hauling them down would probably be your best bet.
