This could be as close to HELL AS I GET !!! ahh maybe not!!!
Well... went to Carlsbad Cavens National Park... Wasn't to sure on going down, but once you get into the elevator and discent 800 ft below ground you change your mind and check your shorts real fast. We had a once in a life time adventure.. Pic to follow.. It was great .Took the elevator 2 mins to descent 800 ft. ( the natural entrance is a one hour walk straight down and we we're told it was hard on the kees and the back) the Caverns were alittle damp but a nice 57F at all times, took us 2 hours to walk through and well worth it. Went to the restaurant for a drink and did some shopping 800 feet below the earths crust.. Hard to beleave..
