when i was teenager we used to go caving in western nc, henderson county.
one we went to you had to crawl on you belly with a rock the size of a 3 bedroom house hanging above you. you had to be skinny to get in there and talk about dark!
cave dark is the darkest dark i have ever seen. i mean inky dark! and ofcourse we NEVER had flashlights! we just crawl up in there with bic lighters!
never told anyone outside party where we were going!
then there was a presipice inside where some one had built a 2/4 ladder that went down about 20' shear.
wow were we crazy!
