We had a conversation just last night about this very subject. We can see how the data "experts" can analyze the sales by NH Liquor stores and then take population and come up with a high per capita figure. What they can't do is determine who is buying, and where they live.
While we (our small group) certainly do all we can to keep the NH per capita figure up, we also know that when we go to the stores, especially in the May to October part of the year, odds are that NH plates in the parking lot are outnumbered by ME MA RI CT NY NJ plates.
Bottom line, reports like that simply use stats to tell their side of the lie.
