My hubby and I decided that in order for my daughter to really learn, we need a riding ring. The area we have to work with is small so it can't be one of those big fancy show rings. It will be grass still and be used about once a week for my daughter's lesson. We measured out today a 50W X 100L Area and it seems like it would work well. Being that she is 5 and for a while is working on trotting and going over flat cavelettis, we thought that was a good size. If she ever gets to the point of jumping and stuff like that she would be taking lessons at a training farm.
