You know where your favorite local coffee shop is at home, but when you travel, likely all you'll be able to find is Starbucks and other big corporate chains. Want to support mom-and-pops? Check out Delocator.net, where you can plug in a zip code and find a non-corporate cafe, bookstore, or movie theater in the area.
It looks to still be a work in progress, and you can help by adding your favorite local shops to the site. I love this one!
