"Within sight of"...?!

It seems to me that "within sight" is too easy, and dilutes the honor associated with this prestigious award. ;) (Besides, there are certain graticules where practically the entire thing is within sight of a pub!) Then you run into the whole problem of: if your geohash location is on a hill or mountain overlooking the city, you can see dozens of pubs! Etc.

I suggest that the award be changed such that it is only achieved if the site falls AT a pub. I would say that the sidewalk in front of, parking lot associated with, beer garden, and similar "extensions of the pub" should also count.

I didn't update it, because I wanted to give a chance for discussion and, in particular, the author to consider. Ted 14:50, 2 June 2008 (UTC)

There is some precedent for the "nearness" factor, and I like the "within sight" limitation. Our hash yesterday was one block south of a pub, so I argue for at least that nearness to be included. Perhaps "3 blocks and you have to be able to see it" would be good? --Thomcat 07:14, 29 June 2008 (UTC)

Probability of landing in a pub?

Through some calculations, I've been able to deduct the probability of having a geohash land in a pub:

I got this by getting the number of pubs in a few countries (UK, Australia, Israel, China, France, Canada, Mexico, Argentina), getting the average and multiplying by 190 (Countries) for a total of about 2,000,000 pubs (Note: I used tripadvisor.com for this, so this is only for buildings with the word 'pub' in it's name). The average square feet for a pub is 2000 feet squared, so 2000 squared (4,000,000) times 2,000,000 (pubs) equals 8 trillion square feet of pubs around the world. The land area of the world is 1 and a half quadrillion square feet.

A 8,000,000,000,000:1,600,000,000,000,000 ratio equals 0.5%.

Umm, I think I did something wrong, my original calculations said 0.0018% chance which I think is more probable. If you notice what I did wrong, or if I'm right, please tell me. I just wanted to put this here before it goes or doesn't go onto the Pub Geohash page, but a 1 in 200 chance doesn't seem likely. I was writing this section after I did the original calculations, but I'd only gotten pubs from UK and Australia and estimated pub sizes. Please correct me.
