HOUSTON Dr. Tom Perez of Houston has spent much of his life planning for the worst.
The retired chiropractor, husband and father of three always keeps an emergency bag close by. Inside are medicines and supplies he may need in the event of an emergency.
Perez said his greatest fear is a dirty bomb, and he fears he will live to see it.
You cannot over prepare for a disaster, he said.
His family was recently featured on the National Geographic Channel s series Doomsday Preppers. The show is about people preparing for disasters.
Producers went to the Perez family s 700-acre compound and safe house west of San Antonio.
Within the barbed-wire fence and bulletproof walls, they showed just how far prepping can go.
There is a scene of Perez throwing Molotov cocktails and another scene of him experimenting with an IED. His children practice living off the land and take part in lifelike drills with actors.
Some people say it s extreme, Perez told KHOU 11 News. I just say it s a way of life.
Jeff Newberry, of Houston, owns an online company called Longhorn Firearms and said some preppers go there to shop in private.
He said they come from different classes and different parts the country.
It s like that little secret society, he said. They don t want people to know because if something does happen you re going to be the person that s going to be attacked.
Perez said he is not too worried about that.
He said he went on TV to help other families prep and that he kept a few secrets to himself which won t be revealed until doomsday.
Doomsday Preppers airs on Tuesdays at 8 p.m. on the National Geographic channel in Houston.
