Spent a couple days surveying with the NSS in southern Ky. The two caves we worked in have as much surveyed passage as many Ohio parks have trails, and there's more to be found that has been discovered. I got to see one room with a huge 100+' cathedral-like ceiling, roughly 300ft long. Unfortunately, It was impossible to photo with my wee flash. Apparently, those sorts of rooms aren't uncommon in these systems.
