Google Maps

Google maps are an excellent tool. I have it on my phone and it's invaluable for planning trips. I would also suggest taking a look at Google Earth, especially Westport as it's in full 3D. Google earth is good for dropping place markers for places you visite. I especially like revisiting places I've been skiing and looking down the slops and measuring the distances we travelled skiing in a day. Not much else to say but I could spend al day exploring Google Earth.
