Where's The Nearest Bomb Shelter?

I was chilling at home yesterday, talking with a friend on the phone when suddenly the sirens started whaling. I could hear them on my side coming from the back of the house and I could hear them on the other side of the phone at my friend's place. She lives down in the valley. Of course I freaked out! What the hell? I'd never, ever heard sirens here in Switzerland before and now it seemed like they were blasting away all over the country! I thought, is this a joke? Is someone actaully attacking the Swiss? Must be a poor guy with no Swiss account over here!

My friend put my mind at ease. She told me it was "just a test" they do once a year. JUST A TEST?! A test for what? In case the bombs start falling? And if that's the case, where the hell should I run to? Questions, questions. I could hardly wait for my husband to get home so I can get some answeres!

My husband confirmed that it was only "a test" and appologised about a million times for forgetting to warn me that it was coming! Yeah, thanks! He said if there ever is a real bomb allarm, we should run to the designated bomb shelter. Where would that be then? He had no clue! Great! We don't even have a basement! My husband was fiercely insturcted to find out where the bomb shelter is immediately and report! I mean what the hell does he go to the army for then?! He tried to reasure me that the chances of anyone bombing Switzerland were slim to none, but those bloody sirens really freaked me out! It's the most terrifying sound one can ever hear! My husband said we have more danger of the damm at Arnensee giving out and flooding us over here than getting bombed. He said those sirens will also sound if that happened. So I asked what the procedure was in that unfortunate case, what should we do?

Go up, he said.
