Supporting local beers

Give more Bingo Points for drinking local beers near where they are being produced.

Ideas include doubling points if you're within 5 miles of the brewery/brewery tap. So if you're drinking Firebrand in Launceston, you'd get 4 points for the first time and 2 points after that.

Or having an additional local Beer Bingo grid that only allows beers to be counted if they are drunk within x miles of the brewery tap.

Or modifying the scoring on the grids so that you get double points for local beers. This would obviously be 20 point on the easy, but also if you get a line of local beers you'd get 200 points for the line rather than 100. If you have 4 local beers out of 5 you'd get 180 points, 3 out of 5 gets 160 etc. Would scale up to the grid as well.

technically more difficult would be to have a sliding scale, 1 mile or less, 100% extra points, 2 miles 80% et
