I'm glad to hear you liked it =)

What comes to the 'mountain main in a city'-theme - I often think that in man-made environment there are so many things which don't have instructions printed on them, or if there are, they are printed in small and you don't always have time to stop read them carefully. That's why I often observe what the others are doing to figure out how to use this or that ordinary elements of urban city-life. Like a plain ordinary thing like riding a bus - is there a different price depending on how many bus-stops I'm going to travel, how do I buy ticket etc. Figuring all that out by reading instructions takes a lot of time, and there is a stream of people trying to board a bus as quickly as possible, so the only thing to do is to go with the stream and guess the best one can =)
