A bit off topic, but the proliferation of maps and GPS is not celebrated enough IMHO. It's such a mind shift regarding freedom of movement - as a kid (1990s), going somewhere new carried a strong risk of getting lost, so we rarely ventured far. Even if we had maps, they were not detailed enough, and it was difficult to figure out where you are exactly. Many from my parent's generation (now in their 60s, 70s) never learned to work with maps (with or without GPS) which limits them to travel alone only to places they already know. There are also other factors (ability to call for help, looking up your travel connections etc.), but IMHO the detailed maps + GPS is the biggest factor in this mindshift where travelling/exploring anywhere is easy and accessible to anyone.
