After Bhul we kept getting lost
because rather than taking a map for that short leg,
we had written down the names of the places on our route
but unfortunately we had written down the name of the
district not the town. The GPS on the iPhone wasn't
working either because we only had a Swiss SIM card.
In Erzingen we stopped at a bakery-café and
asked directions. The baker recommended an alternative
route through Hallau. It was a good choice, some long
hard climbs but magnificent views through the vineyards.
We were back in Switzerland so the GPS was working.
