If you could go on the ultimate bike trip, where would you ride? What would you bring with you? For Jasmine, it is her violin and her dog.
"The advantage of a paper map is you'll never need batteries or worry if you have coverage."
There are many advantages to carrying a paper map. You can read them in bright sunlight. You can hold them at arm's length, or hold them close to your nose. You can use a pencil to draw notes or add roads or mark routes.
I've done a lot of traveling (http://gamut.neiu.edu/~rkastig1/bikehome.html) I started in 1993 when a paper map or copies was all that was available but then changed over to digital maps. I can['t really explain this but I've found that paper is better - and it's hard to come up with a real reason why.
A decent paper map and a reliable compass should be in every traveler's kit.
