Rate your neighborhood on its walkscore

Thanks to Sightline's post, I stumbled onto a web service called walkscore.com. You key in you address, and it calculates how walkable your neighborhood is. I love the idea. But I was a little dismayed, at first, to see that my neighborhood only scores 54 out of 100. And I feel my neighborhood is extremely walkable. I guess if I can add any insight, it would be that walkscore seems based on an urban-dwelling, 20-something's view of what it's cool to walk to: bars and movie theaters rank high, and farmers' markets, kids clothing resale and family-friendly aren't on the list.

That said, have you calculated your neighborhood's walkscore? What do you think?
