Two things we have gathered from our time so far in Italy:
1) When a sign says it will take two hours to walk from one town to the other, pay attention to that sign. Pay even closer attention if the path between those two towns is a hilly, rocky demi-path that will cause you pain and existential worry if you cannot see what’s in front of you. Pay the utmost attention if it the sun is setting, leaving you unable to see what’s in front of you.
2) You might have just transferred from a train whose ticket was attached to the one for the train you’re currently on, but that is not enough for the onboard attendants. Forget to read the fine print on the back of your ticket that tells you to “validate” (and don’t be told what “validating” means) and you will be fined an outrageous amount in front of a crowd of smug, Italian onlookers.
