This is one of the coolest sites out there. You can input the address you either live in or are planning to purchase in and it lets you know the "walkscore" of that property. Your walkscore is determined by how close you are to parks, trails, stores, restaurants, entertainment, etc. The higher your walkscore the less likely you are to have to depend on your car.

Here is an example of a pretty good address based on walkscore: http://www.walkscore.com/score/1111-Hermann-77004
Have a great holiday!!
