Bored? Try Happy Mappy!
This is a cool utility website. You plug in a zipcode or a city and up pops map plots showing the cool things to do around town. Stuck in a backwater village while on travel? Use this to find something around town to occupy your time.
Most of the points of interest have websites attached as well, so even if you are familiar with a park, museum or local watering hole, check out the websites to learn more about it. Thanks to Gadling for the tip.
