There are 3 orange juice processing firms located in CA, TX, FL. 
Costs are lower in some states than others.  Why? If this is true then
why does not just one state produce all the orange juice for the U.S.
market? I would think that factors such as weather and other
environmental factors that would affect the growth of oranges would be
one factor and maybe such things as poor management and lack of
workers.  For the second part, I would think that if one firm produced
all the orange juice for the US, this would create a monopoly.  I
would like to hear what answers someone else might have.
