Single decoction success

This morning I brewed ten gallons of my Bohemian Pilzner. Presently it's fermenting away like a champ down in the lager chamber. While the pilz is in primary fermentation, I think I may attempt to fit in another ten gallon brew session before Iz takes off for Seattle next week. I'd really like to get rolling on this Belgian, however I don't want to sell myself short, and get all my fermentation vessels tied up with aging beer for an extended period of time and be stuck with nothing to drink.
