And also... yet another thing I wouldn't have to worry about -- Radon. I am on the condo board and one of the units tested up at 8 PCL and 4 is the safe limit. It was a reminder to me that I have to test my unit again -- it previously came back at 3 PCL. Radon can change with the seasons so

But if I lived in a car it is another hassle I wouldn't have to worry about.
