I used to spend tons of time circumnavigating some camps to look for gaps in the fence. Now I just pick a section of fence that's far away from the camp and either toss a nade at it or drive through it. So what used to bug me in reality happens few enough times that it doesn't bother me. Especially since they can be broken without detection. The few places where fences that have concrete bases used to actually bother me more, because those can't be broken by any means. The I realized if there weren't any such places they couldn't make you work harder to exfil certain areas.
