so what happens when it rains and you have the storm doors closed? The condensation and general air quality would be horrendous!
Correct me if I'm wrong, but if it actually rained, being in this would be similar to climbing into a trash bag and velcroing it shut. you might not die of asphyxiation due to the air let in by the velcro, but I would think it would feel like it. You would also be sweating like a pig.
Am I missing something? It just seems like it would be a miserable space to escape the rain, as well as being terribly fragile?
