Okay, what was wrong with your friend??
See, that's another perfect example of Karlovac mind - we adore it for ourselves, but if someone from NETHERLANDS moves here we do think that this person has some....well...issues
Main problem in Karlovac is that it's definitely town that was put back most by the war in all Croatia. Some other towns were destroyed even worse, but most of those towns were either pretty boring before as well or are at sea so they developed again with tourism soon enough. Now I am talking only about fun, nightlife, etc...
So, now you have situation that Karlovac is certainly more interesting then any western european continental town of 60,000 inhabitants - but we are still pretty disappointed. I mean, I don't know that for sure, I am supposing that with experience from Scandinavia or Austria, maybe in some countries it's different. Before the war just between rivers Kupa and Korana (that's old center of town, actually huge fortress built as protection of Turkish attacks - so, yeah, old center of town is actually huge military fortress for about 10,000 people), and that's about half mile, was six discoclubs, dozens of terraces always filled with people, live music all around, and more days with open-air events then those without it - now it's quite opposite.
But, Karlovac always had some crazy spirit, here are few funniest examples:
1) in the middle of the war - 1992/93rd, German punk band played in town, so imagine the scene...old center destroyed and dark, almost no lights on the street, and they enter small club in the middle of that center, just next to completely destroyed building, and inside they see naked waiters - naked simply because they felt like it, and, among others, croatian basketball team player that just won silver medal at Olympics, drinking with us in the dark club in f***ing destroyed town.
2) Beach party - that's one of my favourite memories. Few days before town was under heavy bombing...middle of the summer, terribly hot, and nobody is out, people still bit scared...and then out of nothing, some gang starts to give flyers and stuff for "beach party" (all rivers are forbiden zones, nearest available beach 50 miles away) next night...and they just say "take water pistols with you". So, in the middle of town, again in surrounding of gray and destroyed buildings, few hundred people gather with water pistols and similar stuff and simply splash each other for no reason (that was NOT tradition or something, it simply came out of nothing), and few minutes later, older people come as well, from those buildings...50 year old houseviwes throwing bags full of water on people's heads, absolutely nadrealistic stuff - but it was one of the best nights in my life).
3) we are small croatian town, but we were extremely small yugoslavian town
And yet, Karlovac was first ex-YU town with condom machine, second (before Zagreb, only after Ljubljana in Slovenia) with porno cinema, and as another funny fact - only town in the world with fans that in large numbers go to away games, but very few of them are supporting team on home games - they come but they sit and watch - explanation: "I don't know man, it's kinda stupid to yell here, it's better to sit and drink beers".
Yes, I'm journalist, although it would be better for me to be student as well
I started Informatics College during war, and then during summer I used to work for local papers for extra money - they offered me a job, and later national daily paper called me, and, bye bye my college
