That would probably be R2elk in Natrona county, WY. I dunno... it works for him and it gets pretty frigid there. I already tagged him though and I don’t want to pester. I believe it was about 4” thick and of course you have to replace the manure every fall. It’s insulated by the ground around it. I might do it next year. This year winter snuck up on me, but most days carrying fresh water isn’t that big a deal so I’m not too worried about it.Someone here did it successfully...it was in a brutally cold environment too.
Member name is not coming up in my mind tho.
Lucky me! 
This is definitely the place to be if you want to learn something new every day!
