In reply to Susannah2010: In the Peak you can have two groups of 30 or more on thew same crag. They didn't post it on here and they made no concession to other crag users, with numerous top ropes, a 'picnic' across the path, several dangerous practices etc.
Your posting on here show consideration and resposibility. Enjoy you climbing, and I hope your new members take to the sport and continue to enjoy the thrill and skill of it all! Popst a trip report.
