from berlin, amy kellogg is there. i can't believe it's been 30 years, i guess i'm revealing my age. man, oh, man, it seems like yesterday. >> i know, neil and actually the berlin wall has now been down longer than it was ever up. if you can believe that. the 30 years is a special anniversary. and chancellor angela merkel and president bush pointed out that democracy cannot sit on their laurels. there's plenty of dictatorships and repression around the world that need to be stood up to. the fall of the berlin wall was a joyous occasion. it was spontaneous by an east german official on a new travel regime that would eventually allow easterners to go over, and they flocked to the wall and in a couple of days it was over. it's been a trying experience.
