If you are planning on coming to Sierra Nevada, make sure you book a tour a week in advance (at least). They are fantastic: fun, informative, technologically amazing, and if you're lucky, after they prime you with 6-7 generous free samples afterward, you will see Steve hanging out at the bar. He is very friendly and of course loves to talk beer with people. I've lived in Chico for a long time and seen and spoken with him occasionally on my trips (2 mile bike or drive) to the brewery.
