What's Happening?

Just remembered that time I was in Paris on Bastille Day without knowing it was Bastille Day ('sure are a lot of jets flying round and I didn't know the French liked bunting!') and then later, when getting to Berlin, not knowing that Obama was giving a pre-presidential speech there that day ('what's with all the guys in suits and sunglasses walking round the Brandenburg Gate at 4am??!').

It kind of makes me wonder what goes on each day that I have no idea about because I don't go on local free tours every day of my life (which is the only reason I found out about the aforementioned events).
