I'm a 69! - Honest
I just did my walk score, I came out a 69. Personally I think it should be an 89 and they've clearly missed a few things. We only need another point to make 70 which puts me in a "very walkable" neighborhood.
On the other hand, I can see we probably lost some points, they list amongst known issues that in some places the weather doesn't lead being a good place to walk regularly. That much I can get, it rains more in Austin, and harder than it does in London! Really!!
The only reason I can put up with it, when it stops raining it's 90-degrees. Sweet.
What's your walk score?
