Nice gallery of Russia. I spent 5 weeks in Saint Petersburg only and took many pictures.
I enjoyed my stay during mid-September to mid-October 2005, Autumn time.
Saint Petersburg was beautiful when I was there, but unfortunately I did not get to visit some of the famous places.
By the way, I like DSC_0086 and IMG_0923. Question for you, why were some shots taken with Canon camera. It seems that you had couple of good days in Saint Petersburg and Moscow.
I may visit during the winter months and see how it goes.
