If you get a ticket for going through a stop sign in a parking lot that is on private land(e.g., grocery store parking lot) you can challenge the ticket and get it thrown out.

I have heard that too... But, only if those signs on private land are non-DOT signs then the ticket is challenge-able. If they are "official" DOT spec signs then the ticket can perhaps hold up in court. I do not know if this is in fact true but I heard something to this effect several years ago.
