Sharing your location is all the rage these days. MapQuest is getting in on the game by introducing a Facebook sharing feature.
When you have a map of a location pulled up on MapQuest, click the Share link with the Facebook symbol next to it.
You'll be prompted to connect with your Facebook account to get permission for sharing. Then you'll get a box where you can put a note along with the map you're sharing.
