After one of the hardest gathers off the spring range I've ever had. Cows are scattered and 20 miles from a corral. By the time I get around them, I don't have enough daylight to make it to a pen. I've really been considering a portable corral with a semi load out. I called rawhide and was quoted 21000 delivered. Looks like a helluva good set up, but I think ill just go buy a bunch of good powder river panels for a lot less money. FH last year I bought a fully sheeted powder river tube and ally with no backs. It was older and had not seen many cattle run through it for 5250. That may give you a starting point.
