I'm surrounded by forest. We have pretty robust volunteer fire fighter program as we are all in this together. Last year and year before we had 200+ people show up every time we had a wildfire. The county has a helicopter with a fire retardant tank, as well. BUT, if a firestorm comes my way, I want to be able to hunker down for a day in a fireproof shelter.
I am interested to see what you folks do for forest fire preparedness. I have been researching. The biggest issue I am seeing is ventilation. I have read that if you can pressurize your shelter with an o2 tank you can keep smoke out. The other way to go is filtration. There is company that specializes in above/below ground fire proof structures.
For an underground fire proof bunker with air filtration from these guys you are looking at around $100k. At this point, I can't really justify that expense.
So I am considering just building something myself. This wouldn't be long term. If the nukes fly I am not interested in surviving in a post apocalyptic world, anyway. I will run toward the blast. I just want to be able to breath underground and not be cooked for 24 hours. So, anybody done anything like this?
