Karst has special interest to me from the 10 yrs that I was a cave diver.
Will be judging in Chicago Area next week end - Drunk Monk Challenge @ Aurora

Schlafly is a good friend to homebrewers. They hosted our BJCP classes and exam. I have some of their whisky barrels used for the oak aged RIS and BW. Just picked up a big box of 3 yr old E.K. Goldings for a Lambic project.
