Believe it or not, the government still maintains a huge helium reserve
for use in blimps.
Every time somebody tries to get rid of it, some buricrat saves it for
political reasons.  I think 
there are some high paying cushy jobs associated with it, and it employs
the majority of 
people from the area where it is.  I just can't remember where.  I heard
about it on NPR a few 
years ago.
