The last two wars between the Swiss and their neighbours were in 1531 and during Napoleon - who in the end admired the Swiss confederacy and helped rebirth it in its modern form.

For us it was a schock, versus the usual "you can pay it is yours", first come first served that we had back in Portugal.

However while not living in a bunker, we did have parties in some somehow converted into clubs.

Then I graduate and enroll in a cushy university (UCSD) and come to find out, they're also having growing pangs, and so in the middle of campus we found ourselves taking classes in Quonset huts. These Quonset huts were bona fide military surplus, though it was already 1990. https://en.wikipedia.org/wiki/Quonset_hut

The Quonset huts were extraordinarily different from the classrooms and lab facilities we used on campus; they were, of course, comparatively set out in the wilderness, and very rough accommodations overall.

However, I was a commuting student, and nobody was living in Quonset huts, so after our hourlong class was dismissed, I was able to retreat to the relative comfort of home, or the Theodore Geisel library.
