At Porcupine 30, 1, 105, is a signpost, anchored (parent prim) on private property. Attached to this signpost is a sign advertising land rentals, which, in and of itself, is not bothersome, except that it crosses over a linden road.
Normally, things that cross over linden road, if they contribute (or even detract, in my opinion) to the landscape, I think, no problem. The only issue with this sign is that it is advertising a private venture. To me, this is an inappropriate use of Public (Protected) land, and I believe this should be removed, as leaving it would appear to be showing favoritism by the governor's office.
