In the evening we took a ride in one of the most beautiful subways in the world. An interesting incident took place when I gave a 100 ruble note to purchase the metro token, however to my surprise the lady at the counter blatantly returned the note. She questioned me as to where I got the note from and I told her probably from the Uber driver last night. She mentioned its a shame since it was a fake note. She also brought to my notice that it is mentioned on the note in Russian language that this is not an original currency. To her curiosity she asked whether he was Asian or Russian to which i answered he was Russian probably. I got really disappointed knowing that I was fooled and started to recall that since the driver a previous night returned 2 hundred Rouble notes to me (when I gave a 500 Rouble note) and there was no light in the cab, he may have smartly handed over to me a fake one out of the two. I further analysed the fake note and its paper quality was different from the regular note.However, I kept my disappointment apart and purchased the metro tickets with a different note.During the ride we got down at several breathtaking stations (Komsomolskaya, Novoslobodskaya, Mayakovskaya, Kievskaya, Taganskaya, Park Kultury) of Moscow city. Each station is unique in its own way. The Komsomolskaya metro station represents the high point of the Soviet Government. It is adorned with eight mosaic panels designed in the style of ancient church architecture. Also, one should not forget to rub a dog’s nose for good luck at Ploschad Revolutsii station. Eventually after a splendid day, we walked back to our Hotel again walking past the Red Square & St.Basil's Cathedral.
