Now I have a question similar. If you're boondocked somewhere on public land, should you feel encroached if someone else pulls onto "your spot" and proceeds to set up?
Some of my favorite sites are very large, easily room for a bunch of RVs. Only once when I had arrived was someone else setup in "my spot". Being a large field, I could have easily parked next to them and we both had plenty of room, but instead I moved on to another site that's a bit trickier to get into.
Few things are more annoying than to have someone set up right next to you when there is plenty of room to park elsewhere. This topic as been discussed at length on this forum before and I think the consensus is on the side of solitude.
