Bert Sperling, who has been compiling information for almost two decades about the best places in the country, has developed a list of the most difficult cities to navigate. Sperling used Avis's mobile-phone assisted navigation, Avis Assist, and Motorola to figure out where people are most navigationally challenged, using factors like street layouts (grids, diagonals, windiness, one-way streets), congestion, bodies of water, and complexity of directions from city to airport. The top ten most difficult to navigate cities are:

1. Boston, MA
2. Washington, DC
3. San Francisco, CA
4. Baltimore, MD
5. New York, NY-Northeastern NJ
6. Ft. Lauderdale-Hollywood-Pompano Beach, FL
7. Los Angeles, CA
8. Seattle-Everett, WA
9. Providence, Pawtucket RI-MA
10. Norfolk-Newport News-Virginia Beach, VA

While the study is geared towards business travellers, especially ones who drive, Gothamist still felt it was interesting. Our perspective is from the pedestrian's point of view, and the city can be easy to get around, if you're in Manhattan's grid and have a basic knowledge of how the streets and avenues work. But if you stuck us in the West Village, we're wandering around the same tree-lined block for ages. And in Queens - forget it - it's like 46th Street or 46th Road or 46th Avenue or 46th Boulevard. Which is why Gothamist loves the subways, buses, our cellphones, and all the kind people who give us directions when we're trying to get somewhere. [Via CNN]

Brace yourself for out-of-towners during next week's convention. And do you find yourself giving people directions on a regular basis because you have that look about you? Or are you so sure of your direction-savvy that you insert yourself into tourists' conversations? Gothamist thinks this is an interesting, untapped area for discussion.
