for Best Biking Roads.
I have a Garmin so use Garmin Basecamp to plot the routes (download for free). A lot of people moan about it and it sure is quirky and quite slow an clunky if you don't have much RAM but once you get in the swing of things I think it's good. I used to plot everything at home and try to envision every outcome and plan for it so I could just pick a pre-planned route when away, because plotting a route direct on the SatNav is murder. Last year we had a big change of plans while away so I sat down in a restaurant to plot a new route. In the end they were chasing us out because they wanted to close up and I still hadn't finished
So when I got home I bought a 10" Lenovo tablet/laptop which takes up next to no room, downloaded Basecamp on to it and plot routes with no trouble wherever I need to. Because the Lenovo has nothing else running it works much quicker too - marvelous
As a bonus I can keep all my photos backed up on it too, rather than just relying on memory cards in the cameras.
I used to religiously buy maps as a back up but I never seem to use them now since Google Maps and Google Earth are so readily accesible.
