I visited first time in 2003, and was dismayed. I posted to the Stone Pages forum on the matter too

I made some phonecalls, and no one seemed particularly bothered about taking responsibility or ownership of the problems. I wrote to English Heritage Northern Region, but have never heard back. This is an over-used and badly damaged site, and needs a pro-active plan of management, but I don't think it will happen.

Good luck to you; may you have more than I. I'll back any sensible action on this.

Cheers
