I'm sitting in my camper playing on my computer when along comes another couple for a "tour" of my teardrop. I could easily overhear their conversation as they were approaching...
wife: "honey, she looks like she's busy maybe we shouldn't bother her"
husband: "nah, it's fine, I'm sure people are bothering her all day to see her camper"
Listen to your wife!! my camper is way too popular!
I guess my "bear" sign is not a deterrent!
