I rather miss using a routesheet and enjoying the route 'as written' by the routemeister (in good weather, anyway), so I had the genius idea of phoning up Garmin to get one of those pesky mount clips which screw onto the back of an eTrex Legend/Vista (available gratis on request). Plan is to screw it onto the back of an old perspex maptrap* so I can clip it onto the GPS bar mount, and leave the GPS in my saddle bag for when I get seriously lost (as if). An old chain ring bolt will be perfect for mounting Maptrap onto the clip. Sorted.
* A piece of plywood with bulldog clip would do just as well.
