Satnav + Mk1 brain and eyeball = WIN
I refused to get a satnav for years: they were the devil's work, maps were better looking etc etc.

Then I had a week in which I had to physically carry the following from one vehicle to another: Truckers Atlas GB (with the bridge heights), London, Cardiff, Birmingham and Bristol A2Zs, county maps of Somerset, Gwent, Glamorgan, Gloucestershire, Berkshire, Essex and Norfolk, plus sleeping bag, laptop, DVDs, clean clothes and a BIG pack of babywipes. And all that had to fit on a motorbike at 0300 Monday, and come home again at 2300 Friday night.

Bought a Tomtom, downloaded the bridge POIs, and used common sense. It helped that I've been driving HGVs for 20 years; you get a feel for unsafe side roads.

These days I drive the same route every night, but the Tomtom goes in so that at any moment I can plan a diversion and calculate ETAs. Handy last week when the A1/M1/M62 went to tits around Sheffield/ Leeds.
