Yes, please. If you can get to the swimming pool/kill zone, please look to see if the wall on the deep end has a way of opening up. I feel like there's a tunnel for minisubs to enter and exit. It's just a hunch, because I've researched the karst areas and waterways that are close to the Biltmore grounds. It doesn't seem possible, unless there's a aquafir that I'm unaware of, but want to check all bases. Thanks. Have fun!
