After some time has passed and everyone has calmed down, perhaps you could suggest to the BO to put tie racks outside the barn . And with a 4 x4 post , a couple of hooks, you can set the post 4 ' tall, use the extra piece with an eye at one end and make a saddle holder near the tie racks. It keeps the Barn aisle clear , allows everyone access at all times.
Ask the BO to post feeding times. Lessons etc can be scheduled around feeding times.
Having the Barn Aisle clear is also a safety precaution, what would happen if there was a fire or an injured horse that required immediate attention, or one that was cast ?
