I gotta tell ya, I rarely leave it alone at the mercy of other driver's. I usually drop Lynn off and go park at the back of the lot and wait. I'd like to shop with her and I would park at the back of the lot all by myself, but someone always decides I have the best spot (safest) and parks right next to me. GRRR! At least I drive back and pick her up. And we never take it to crowded parking lots anymore. Matter of fact, I have left because I couldn't find safe parking. My wife thinks I'm nuts, but appreciates the care I take of her car.
