https://triproutemap.com was a weekend project that was inspired by a plan to buy a one way ticket to the middle of Europe and wander for a couple of months.
It's fun! You can use it to plan trips, get a **very rough** estimate of how much it would cost, and create a plan for your exploration of the world.
Currently, I'm pretty set on starting in Florence, Italy (per the recommendation of multiple people). I want to visit the Jungfrau region in Switzerland and maybe give Denmark a try. Greece sounds amazing as well.
