Forgive me if this has been posted already but I didn't turn up much in the search.
What's your walk score? http://www.walkscore.com/
Put in your address and this site tells you what businesses and services are within walking distance of you and generates a walk score for your addresses based on the amount of things within walking distance.
My house got a 52 (out of 100)
7 grocery stores within 2 miles
8 restaurants within half a mile
7 coffee shops within 2 miles
8 bars within 3/4 of a mile
1 theater within 2 miles
6 schools within half a mile
7 parks within 1.5 miles
5 libraries within 2 miles
3 books stores within 2 miles
7 gyms within 2 miles
1 drug store within half a mile
7 hardware stores within 2 miles
6 clothing and music stores within 2 miles
I just moved here 10 months ago so this is also helpful for me finding some nearby places, though some of the stuff is out of date (I know some places have changed within the short time I've lived here).
But still a cool service to show you what's within walking (or biking) distance of your home.
