Thank you! I'm pretty sure I've seen some great things in your journal too on some occasions, as I'm fairly certain Tooticky has linked to you before.

The fences are there to keep people from taking too many walks on the mounds (as they used to do, up until 7-8 years ago), since they are historical sites and old viking burial grounds. But they are more than that too, there really is a lot of old old magic around that area, and people still walk up there sometimes, fence or no fence.
