So I read up on how to do join up without a round pen, and it was suggested that you cut off a part of the arena with jumps so it's a square or an octagon. However I don't think I will be able to do that because most of the jumps are stored somewhere else.
So I was wondering if it would work, if I lunged first, and then took off the lunge line and continued to chase the horse's hind end. Do you think the horse would go in a circle around me? The arena is very large: 240' x 120', but in the middle-ish there is the large wooden mounting block, some poles and standards. It sort of makes 2 separate work places, but one of the sides is a bit smaller so I was thinkign of doing it there.
Suggestions, ideas?? I really don't think I can find anything that is safe to block off an area.
