Here in Michigan, we've had no He shortages. Interestingly our supplier
mentioned that he was not aware of any shortage problems in other parts of
the country either.

Hmm, maybe this explains why all of our recent liquid helium orders have
been short in recent months.... typically about 75-85 liters instead of
the 100 that we order. Our supplier is Air Products who have a plant in
Renton, WA, I believe.
