Lack of brewing. All of the gear is at my retirement home and we only get there every other weekend or so. Not much time for brewing, what with repairing the lawn mower, mowing the driveway, cutting back the blackberries, watering trees and bushes, as the last weekend went. Also had to unload all of the camping gear from the van and stow it. Drank a couple pints, though.
Remember one unassailable statistic, as explained by the late, great George Carlin: "Just think of how stupid the average person is, and then realize half of them are even stupider!"
