I have never owned a horse property. However about 10 years ago I bought a used 80' round pen, it had been used as an arena 100' x 60' for the seller's daughter who just went off to college and they no longer needed it. I immediately bought an extra gate from TSC.
I've held on to it through thick and thin, moved it to 4 different places, and in many different configurations.
* 2 separate pens, 50' and 30'
* 1 large oval, 100' x 60'
* 1 large gourd shape, using 1 panel and the extra gate to separate a smaller section. This was very nice for using the small section to hold a horse or 2 while working one in the large section.
* 1 80' round in a field for turn-out of horses that didn't get along with others.
* Many others
* 1 place wouldn't let me put it up so it was stacked against the barn. DSCN3254_479.jpg
Currently for the first time it has a sand base and I am ecstatic about it. DSCN4051_1276.jpg
I swore I would never break it up, as in having part of it in another location, but I have. My son moved to a house with a broken down chain link fence and needed a place to keep his dogs, so I let him use 5 panels and the TSC gate. DSCN4019_1244.jpg DSCN4020_1245.jpg
So it is now a 55-60' sand based pen for me, and a 20-25' Dog Corral. DSCN4021_1246.jpg
