There's this road in my home town which has been on everyone's GPS for years. I contacted NavTec and others to have it removed. They wouldn't because I wasn't an "official person".

This lead me to OpenStreetMaps. Now I can add/remove those items so my travels are more accurate. Not to mention so I can know where all the trails and features are. (like that lake I want to try to kayak to... or bridge in the middle of no where... or that... whatever)

My goal is a selfish one. I want to make maps more accurate for my travels... and if others can benefit from my efforts that's the added bonus.
