Compared to today's "restrictions", there were many back then.
Since not everyone had the luck to drive cars, we started tours in the valleys. In Mojstrana, Bohinj, Kranjska Gora, Rateče, Črna, Mežica, at Plesnik in Logarska, Luče,... That's probably the only restriction now (closed road to Tamar), plus sometimes salty parking prices. Back then we didn't see it as a restriction.
We were "restricted" by public transport from home and back. Not to mention border mountains and border crossings. At every crossing, inventory of gear in the backpack, from camera to rope. Gear you could only buy in Austria or Italy, or even farther. Of course you had to hide it from customs. Or you crossed the border with old shoes, old backpack, returned with new ones.
I remember once in Maribor paying a whole salary for two puffy hoodless jackets (Toper).
The next one I had sewn by a seamstress. Not cheap, but with more down and made to order.
At border crossings you could have a limited amount of money. Usually too little for the tour. At the Swiss border you had to have more to be let through at all!
We mostly slept outside. Ah, that was an advantage over today. Which got complicated in the mid-90s when police threw us out of bed in the middle of the night in Tamar and we had to pack up camp. Even though during the day (it was Sunday) some from the most beautiful city were roasting on spits there.
Bivouacs were mostly locked and for locals. In the Logar end I climbed most routes, but only slept in bivouac twice.
On border peaks, border guards usually complicated things, especially in winter.
In winter, huts in high mountains were closed. I didn't miss them otherwise, but there's a difference from today's weekend hut openings.
For an expedition to another continent you had to earn it with high-altitude work. You couldn't just buy a plane ticket and go anywhere like now.
Korl, with the house you missed. I wasn't one of those who squandered the former state. I even paid self-contribution.
