Spelunking / Rock ClimbingSpelunking is the recreational sport of exploring wild caves. Rock climbing is a sport in which participants climb up or across natural rock formations or man-made rock walls.
Air vents seem like a good thing when you are back that far. I am still hoping for a trip next year to get out and explore. Also I want to snag a good camera that I can take with me on the trip, anyone with recommendations?
