Nufenenpass seems to be a bad place for hitchhiking.... we tried it too when we missed the last bus coming back from Basòdino. Nobody stopped in an hour :( In the end my friend had to walk 6 extra kilometers to get our car after 10 hours of walking :(

You have a good friend! Did he walk for you to Airolo? We have acted more in the Italian style (by phoning the mother). However, we found a passage up to Airolo after 1 hour

Haha good solution! Unfortunately, we first would have to fly in our moms :D
We had the car in Ossasco, so at least it was just going down...
