Have a wonderful trip!
If I was smart, I'd type how the word for "bye!" in Russian. So you'll just have to settle for BYE! Have fun!
If I was a smartass I'd say "Yup" which I'm told means "fuck you" in Russian.But I digress. Have a great time! =D
Good luck, have fun! I'll think of something Russian to do in your honour!
I hope that you are having a fabulous time!
