I just thought I would bring this up in Urban Preparedness because I have met a lot of people with no clue about it.
It is just something for some of us to think about if they have not thought about it already.

If you know how your streets are numbered and the main landscape features you stand a better chance of not getting lost.
So does your city number their streets, use the alphabet or is it a random jumble of oddly named avenues?
Is the main grid for your town north and south or at some weird angle? Does the grid change, or has it got a lot of those areas where the streets are laid out like a mess of spaghetti?
Are the lots numbered from south to north or from some topographical feature like a river?
Which side of the street are the odd numbers on?
Where are the major buildings located?
Where are the major obstacles located?

Like I said, just something to think about.
