I'd like to start doing that, but most of the cycle routes round my area 
have no name on signs (for example, the long cycleway beside the A4 from 
Chiswick through Hounslow I assume must be part of some route, but I 
have no idea which). What non-restrictive-copyright sources of cycle 
routes can I use to find out?
