Dec 21st or 23rd 2012, Fact or Fiction?

This one drives me nuts. Should I start saving for a Bunker 5 miles deep under the ground? Or does it matter? or just a waste of time? The Tsunami's are supposed to cover the mountains, so high ground wont work either.
Everyone, well not EVERYONE, is believing the Mayan Calender is the end for all of us. Yes the Mayans are real people, yes they have this dang calender. I just watched a show on TV about these cave climbers that went into the deepest Mayan Cave ever known or explored. They got there and it was nothing but deep mud like quick sand. But maybe it was something spiritual to the Mayans down there back in the day? It sure wasn't spiritual to the the cave climbers. It got very technical instead when their gear malfunctioned.
Personally I think it was cool, but a waste of time. The only wild thing of it all was these cave explorers did it with all the high tech gear available and had major issues getting there, including an injured climber and the Mayans did it back in the day barefoot with no fancy gear. 
I'm kind of in the middle of it all and trying to keep a positive belief of it all. I think it will be the end of the calendar and the beginning of a new one with no disaster at all. 
The talk of a total spiritual change? Doubt it. Too many different spiritual beliefs across this earth. This world cant agree on the smallest of beliefs much less agree on one single spiritual belief. 
We need to consider the most credible interpretations of the information we do possess on the Mayan works. On that note, who is credible? The Spiritualist? The Scientists? Anyone? 
This is a very heavily debated issue and date. Where do you stand? What do you believe?

Me? I'm gonna ask Snopes if this is real or not cause Snopes knows all!
