Speaking of which,
in the Dept. of Whimsy:

For the ocean sailors, (who know that 1 nautical mile = 6,080.27 feet):
1:72,963.24 (1" = 1 nautical mile)

For the mountaineers out there, who know better than I do the height of the tallest mountain in North America: 1:243,840 (1" = 20,320' eg, approximately one *Denali*)
