I know you have a vac sealer.... Seal some up and then store the "bricks" in a couple of ziplocs. OR you could get the jar sealers and store in mason jars. (just remember to make a map when you bury 'em in the backyard )
I would change your money into silver/gold, then you wouldnt have to worry about it. Storing FRN's seems like a bad idea, not matter how you 'stack' it.
I think you kinda missed out on the best time to buy. 10 years ago the evangelical Christians preached getting out of debt completely and buying gold coins. It was cheap then. Does anyone see a bubble coming?
Deal only in cash. Do not, I repeat, do not trust the banks. Government take over of all banks in the near future. You will only be allowed a small withdrawal per 24hr. period. Keep paper $ right now. Trying to deal in gold or silver will draw unwanted attention. Feel sure the government will be calling in all known gold & silver held by citizens before too long. I am not paranoid just careful.
