Mirrors, mirrors, mirrors... just keep checking them, Sols, and take things nice and steady. As someone who still regularly loses herself even on the most well-planned trip, I can say - don't worry! You can pull over at some point and turn round again. Take a 2006 Driving Atlas with you, plus one of the smaller, detailed area books for the county you're driving in. The big atlases are great for showing you all the main roads, but you need the little ones to show you the detail. When I go on a trip I write down all the key points of the journey and keep it on the passenger seat next to me - main roads, junctions to turn off at, and any special instructions from the people I'm going to see, such as, 100 yards past a big sign with a blue cow on it, etc.! (I still get lost at least once, but it's better than lost six times!) :shy:
Now, have you got yourself Breakdown Cover arranged? You really MUST do that, especially as a beginner driver and a single woman. Keep a torch (with working batteries!) in the car, keep a large bottle of water in the boot to top up your radiator, to stop the engine overheating in the summer or in long, slow queues, and keep a ready-to-use windscreen wash in the boot, too. There's nothing more annoying in winter than getting lots of sprayback, and then finding you're down to your last little squirt of washer. Also keep a roll of kitchen paper handy in case you need to clear condensation from inside, or muck from outside, the windows. When you've put all kinds of contingencies in the car like this, you'll feel a lot more confident about dealing with the unexpected!
