I don't think anyone has suggested this one...when you're picking things along to route to use as waypoints, or even the waypoints themselves, have a good look at what is on the map approaching them and use those feature to guide you in.
For example road on stbd leads in from 15 miles out and converges with railway line about 2 miles before waypoint. The other thing that is easy to do is to 'handrail' something like a river or main road, or even railway. Be aware of the bloke doing the same thing the other way though !
I'm sure that nearly everyone had experienced that nauseating feeling of helplessness at least once when you realise that you aren't quite sure of where you are...and the time is ticking on...and the fuel's going down...and it' getting dark...and where you're going doesn't have lights...so break the chain there and then and call 121.5 for help before it gets too bad - they really won't mind.
