You are either reading too fast or thinking too slow. I did not intend to compare our precious p-shell to a Monocot, The point was if any coach has a big hole cut in it for a slide it must have the opening surrounded with enough mass to support the original intended integrity. I didn't mean to ruffle your feathers. You do a great job of helping us all out on the technical side of our coaches.
I thank you for that.
