I am or better we - my better half and me - are curious about what a city can show us. Therefore we do our city tours apart from tourist guides and we let ourself surprised on what will happen. Maybe this is the reason why we are into sciences, we are always looking forward to explore things which are off the books.
Don't be worried, we aren't such geeky as it may sound or as you might imagine if you hear chemist. We are trying to be handsome and easy to handle and it will work most times.
