I sent my backpack forward with the Maille Postale for the two weeks that I walked in France in the fall. I needed more than usual because I brought items to defend against covid: tests, masks, medications in particular. It was a real nuisance: having to make bookings before I could arrange for pack pickup, trying to do everything a day longer in advance before Sundays, the towns that seemed to have no accommodation, when I knew that I could find something if I just walked through. I left behind what I could with a friend in Rabanal del camino, where I had been called on to serve as a hospitalera, and carried my pack for the rest of my pilgrimage. Now I am considering walking shorter caminos, beginning this year at around Easter, as I have never walked a spring camino. It would be interesting celebrating my 75th birthday on pilgrimage in Easter Week. I might like to spend several days in ancient cities to visit churches and monuments: Zamora is one possibility for such a stay, then walking on to Santiago.
What I am trying to say here is that luggage transport can be one way that older pilgrims can continue to walk the pilgrim routes: good for our health, wonderful for our spiritual life. I can still walk with a pack, if I leave behind a great deal and ignore the pain in my shoulders, or medicate heavily. For now, I prefer not to use luggage transport again, if I can avoid it. But pilgrims do not use such a service just for convenience.
