1. When in a city grid whose blocks are different lengths in one direction than the perpendicular direction, and you want to measure the "Manhattan distance" to somewhere, that is, the distance traveled on a path that uses the grid, do you measure in:

a) number of blocks, whatever length
b) blocks estimated by the shorter block length
c) blocks estimated by longer block length
d) blocks estimated by Manhattan short blocks even if you're not in Manhattan
e) distance actually traveled in some standard unit, you refuse to try to measure in blocks
f) same as above but use minutes' walk
g) distance in standard units as the crow flies
h) minutes' flight (of a crow)
Something else?

How does your answer change if you are on a street that cuts diagonally across the grid? I am on a street that I think of as 1/sqrt(2) distance between blocks (it cuts at middles not at corners), but actually the angle is more like 30 degrees off the grid because the longitude blocks are farther apart.

Please answer, I'm actually curious.:)
