How walkable is your house?

How many errands can you do on foot, instead of driving? According to the Walk Score site, our house is a 75. ("70 - 90 = Very Walkable: It's possible to get by without owning a car.") I feel like that's a little low. For instance, I can walk to the post office, and that's not calculated in. On the other hand, under movie theaters we get credit for a psychic reading place. Not sure how that works, exactly. But here's another oddity: our closest coffee shop is not a Starbucks.

Bill Gates only gets an 11. Loser.

The white house gets a 94. But I bet they drive everywhere.
