So, grumbly cavers, find a good SRT manual, stoke the fire, light your pipes, empty your poo-bags, pop a Valium, and stop having a go at the youngsters who are going to be the explorers of the future. If you want to be alone in a cave then go and find one and keep it secret for years (or screw up access). Isn't that what your lot did in the past? Get a grip. End of rant. Coffee time for me.
