Howdy Guy, here's another odd one where the circumstances may be different than they appear.
There's a plot of land in Pierce whose owner no longer appears to be a resident, the land isn't deeded to a group but it is assigned to one which only has two members. Of course they have the old access lines up. If the owner of this land is no longer a member I'd love for it to go up for auction.

This location is the landing point for the parcel (except on the ground). In the end it may simply a case of a database error, but the Owner's profile comes up but their name doesn't appear in search and they are no longer listed in any of their groups.
I'm trying to deal with some of the other people in Pierce who seem to like to have root-prim objects on other people's land, you can leave that one for me! Though you may want to check the protected water on the East side, seems there's a few hundred objects of other people blocking the waterway.
