So, what can I expect there? Just wondering what the overall point of it is, or is it mostly a membership drive, or ? ? ?
They are a blast. One of the purposes is to get new members, so if you know someone, bring them along. But I've also found them to be great places to meet up with other homebrewers, see the inner workings of the breweries, and try some fantastic beer, including some stuff that doesn't get out to the market.
I was at the Allagash rally in May and loved every minute of it. Even found out one of the brewers grew up in the next town from me in VT. And I won an AHA shirt!!! Perfect end to a perfect day.
