Hey Julie,
Sorry it's been awhile since we were chatting last and how great I've got an opportunity to write you a letter!
To start with, last month I participated in the TV quiz show "Around the World", and I was lucky to win two tickets for a tour of Ukraine and I'd like you to come with me there.
I am planning to get there by plane as it's the quickest means of travelling and I've never travelled like this, so I think it'd be a good experience.
When we get there, we'll be accompained by a guide and accommodated in their local motel.
Next day we'll have several trips to various sights, including the Karpaty and the Sofiyevka Park.
Don't forget to take with you some summer clothes and something to hide from very possible rain.
Well, I've got to go now as my show's about to start.
Best wishes,
Your friend,
