maps of beer?

so today i'm hanging out at the Oregon Brewer's Festival and I am chatting with the founder talking about maps.
really, is this a good use of either of our time? not sure, but how often do you get to just sit back and watch the action?
But yes, I think that people are not necessarily looking for maps, but if they were available, they would be used... a lot, pretty sure about that. More when I get back to the computer (I'm mobile).
