Dear Jim!
Welcome to Moscow! I know, you are here for the first time. I lived in Moscow for all my life, so I can offer you some places to visit.
First, you shoould go to Red Square. The Kremlin is beautiful and noble. And St.Basil's Cathedral is also worth visiting. Then, go to the Tretyakov gallery to watcth different masterpieces. Then, if you walk down the promenade, you will see the Cathedral of Christ the Savior. Or, go around the Kremlin and you will see the Bolshoy Theatre.
Have fun in Moscow!
Yours,
Nick
