Well,we want to go to the upper floor so we have to sneak in that very exposed entrance hall of the cinema decor company PicSou...outside this door:Street,houses,cn police building,entrance turnstiles and the guard booth.....We succeeded with the heart beating hard and went back to our bikes....Just by curiosity,we passed by this entrance and the guard was at his desk,looking at us biking along like people going to work at 5 am........
