Isn't it appalling? Those of us who've lived in TV a fair amount of time (in my case a little over 6 years) forget, I think, about the nasty, dangerous world "outside the Bubble!"
When I was showing my home in late 2004 in St. Louis, such precautions never occurred to me!
Guess I was lucky that only the second viewer bought and gave me the freedom to become a Villager!
