Marta, If my recollection is
correct, the best portable corrals are the standard heavy pipe corral panels
which are not that easy to lift, but it can be done, and when put together make
a much safer holding area for the horse. I use these at home and move them
around by myself, but it is hard to carry them more than a hundred feet or so. IF
I had room on my trailer to mount 4 of them, that’s the way I’d go.
