A look at Pier Giorgio's correspondence is the best way to answer this question. He seemed to be almost always on the go: to the mountains, to the sea, to visit the coal mines, to visit friends, to attend Eucharistic Congresses, to participate in Catholic gatherings, to tour the great cathedrals, and so on. He always took time to send postcards and letters to his friends and family recounting his travels. Like everyone, he experienced the inconveniences of crowded train cars, lost luggage and time-consuming customs inspections, but he always remained in good spirits. Here are just a few examples:
"The trip from Berlin to Katowitz was very unpleasant: from 10 p.m. until 4 a.m. I had to stand most of the time, and then I got a seat between two women, crammed into a position where I couldn't even sleep even for one second: I had a bit of room on the way to Breslavia, but it was already six and so I slept for three hours only. Tomorrow afternoon I leave for Regensburg. I'll see the city and then I'll go on to Munich." ~ Excerpt from a letter to Maria Fischer, December 28, 1922
"This morning I visited nearly all the churches of beautiful Bologna." ~ Excerpt from a letter to his mother, August 27, 1921
"I arrived safely in Brenner where I received the sad news that my luggage had been unloaded in a station halfway between Verona and Brenner. Tonight I slept in a first class car parked at the station because the only hotel in this little town was closed." ~ Excerpt from a letter to his mother, September 15, 1921
"At the end of this month, I am going to make a trip on the Rhine, stopping at Heidelberg, Mannheim, Frankfurt am Main, Mainz, Kohlenz, Bonn, Cologne, Hamborn and then through Westfalia and Turingia, I will go on to Berlin." ~ Excerpt from a letter to Alberto Falchetti, October 14, 1921
"This morning together with the president of Catholic students in Czechoslovakia I went to see Prague's major churches and then all the rest....Then later on I went to call on the Apostolic Nuncio....Tomorrow I leave Prague and I will be in Vienna by three in the afternoon." ~ Excerpt from a letter to his sister Luciana, November 16, 1921
"I have arrived in Venice after a fairly good journey. At Tarvisio we were halted for two hours by the customs who were very severe and so I had plenty of free time to admire the lovely mountains. Venice is magnificent and even after having visited many other cities, I think there is not another Venice in all the world even if the Queen of the Sea has a lot of faults such as the narrow streets and the bad smell that the stagnant water gives off. I have no words to describe this city." ~ Excerpt from a letter to Maria Fischer, November 23, 1921
