when you have many things to do but no willpower to get started, you make a bucket list of transportation systems to visit

 1. Hong Kong MTR

2. Eurostar 

3. Shinkansen

4. Moscow metro (look at this map!)

5. Stockholm Metro

I've been lately thinking about ways to become more environmentally conscious beyond the usual sorting of recyclables and compost. Driving less and opting for public transit (if the area permits) would be ideal, which leads me to search for places with good urban planning.
