Started with a taxi ride of 7.6 km (ca 5 mi) then walked 16.2 km (ca 10 mi) then caught a bus the last portion to Porto for about 10.5 km (ca 6.6 mi). Basically, we rode more than we walked for this stage. That upset Hugo more than I realized and when we checked into our little Pension, it resulted in Jean and I parting ways. We had too many misunderstandings that could have been avoided--we're just too different.
Hugo and I explored the old part of Porto: the Cathedral, Libertade Square with City Hall up the hill, and a rest in the same Square with a big beer while listening to great music by a small musical band. Plan to go to Cafe Guarany famous for their Fado music (mournful music about the sea or longing, and nowadays is always about a "loss"--so it might be serendipitously appropriate).
