You probably know at least a few of the footpaths and walks and areas of interest near where you live. If you feel like sharing why not add your expertise to the open street map project. Get out on your bike or go for a walk and then add something to the map. It works a bit like Wikipedia, anyone can add or adapt what is already there. Put your local shops, pubs landmarks on the map and benefit from the exercise that you will get by doing on the ground research.
