Rhubarb rhubarb!

I have found a new companion: rhubarb yogurt. It is delicious! Not to sweet, not too tart, lovely and creamy. I think it might be the best yogurt flavor I have ever had! Zounds, is this possible? I thought that Stoneyfield Farm's blackberry and coffee flavors had it sewed up. Think again!

The question is: can I buy it by the gallon?
