…but I am really scared about the government hiding this from us. I keep hearing about the Denver underground shelters and "let the elite survive" theories …
Governments do hide stuff, this is something we cannot deny. But it can never be at such a massive scale like the 2012 hoaxers claim.
The number of amateur astronomers out there are massive.
Also building an underground shelter for the disasters the 2012 hoaxers claim, is useless. yes some people might get scared of the big bad 2012 and order a bunker under their house just like they did in the 1960's. There is big money to get from builders that promote 2012 just to sell a bunker.
Also regarding the elite. Would you really want to be part of an elite sitting there in a bunker and when you get out you actually have to do the dirty work for yourself and start building your own house, do your own farming for food? No more servants and house builders and farmers. I don't think that the elite would want to be in a bunker when this happens.
What can be is that the government do build shelters at secret locations from strategic point of view to protect the president in case there is a terrorist attack. Shelters might be built but has no relationship with 2012 whatsoever.
