Basically a spin off of the Doomsday Preppers show.
Brent Sr. has a castle up in the hills and is working to fortify it and "prep" it for...um....an apocalypse or whatever, EMP, economic collapse, etc.
These shows are pretty amusing, but there are real lessons to be learned from time to time. What would you do in the case of an earthquake, flood, huricane, etc. What if you found yourself in a Katrina style situation?
