How long was this experience? I have a sense that sleeping outdoors as part of an adventure is getting tarnished by the homelessness and mental health crisis (… which is a separate issue that can’t be appropriately addressed here).
I live in a seasonal touristy area and I have to do double-takes as to whether someone is transient, or is just backpacking.
The implication here is personal safety. The homeless individual could be unpredictable due to mental health, whereas the backpacker is likely to be neutral.
Those were the only two times of outdoor sleep in my life to date. The itinerary was Milan - Zurich - Amsterdam - Paris - Biarritz - Modane - back to Italy, sleeping in either hotels or the closest camping site to the train station.
IIRC it was a ticket for 20 days of unlimited travel, which we had to cut short as a friend did get sunburnt so badly to require a hospital stay. Ah, the joys of youth.
