Once someplace is posted on an open forum then it's open season for the near do wells and scavengers, all of the folk that I have met who regularly post on our forum are decent folk who explore for the sheer enjoyment we get out of nosing around somewhere new and sharing it with like minded nutters.
If you nose around other folks property chances are you will run into an irate owner, caretaker or neighbour at some point, and that can be disconcerting, or as in Telfs case expensive, it shouldn't happen but it does , a few bad bar-stewards give explorers a rotten reputation.
To answer Krela, yes we do have a responsible to insure that our actions doesn't harm other folk or their property, I feel that the members only thread will protect many vulnerable sites.
