The Pastor Pod that is mentioned in a current blog article is missing one crucial component...a pair of noise-cancelling headphones. I lived in a travel trailer for almost two years, parked in a city neighborhood, and it was a noise magnet. I could hear dogs barking 6-8 blocks away like they were tied to the entry steps. The big sides function like a drum head, absorbing and focusing the sound into the interior. Conversations that were half-way down the block sounded like they were happening inside the Box, which is what I called it.
