You've heard of TinyURL now check out Tiny Map. TinyMap is a web service designed for users to create maps that they can then share with their friends.
The site is pretty simple in design, using Google Maps to create a detailed map of any area your choose. One you've located your area of choice you can draw a map to a particular location by highlighting streets in pink, as well as place different colored markers along the route to indicate turns, landmarks, or places to pick up a pizza. The site also gives you the option of typing a brief description for any point on the map so you can write things like "Turn right here, you will see a Burger King" or "Get me a Whopper."

Once you have completed your map you can get your own Tiny Map URL formed to be easy to send party guests, friends from out of town, or anyone else who needs directions. If you like this, check out PubWalk which allows you to create your own Pub Crawl map and send it to friends or your mobile phone.
