re: #116 GeneJockey
Therein lies the problem - the likelihood you’d ever need anything like that is vanishingly small, and building one is awfully expensive, and you only get to feel smart about building one when the rest of you block is destroyed. Otherwise your neighbors think you’re nuts.
Or you’ll get into a fight over it, like in that Twilight Zone episode.
Prices appear to run around 6-7k. Which is a lot of cash for a lot of people.
