Hi Liz,
How are you? I'm really glad that you are coming to Russia in July. I'll gladly show you our famous attractions, and I also want to take you to several interesting festivals. They all take place in July. The first one is the International Festival of Landscape Objects. Famous architects, designers and artists create unusual and unique art-objects. They use only environmentally friendly materials to build the constructions. Some "creations" are really strange and some are real masterpieces. I guess you'll like the Festival of Author's Song. It takes place on the bank of the river and the guests, as well as the participants, live in a campsite. Many famous singers perform there. The last festival is a "Theatrical Yard". This is a kind of street theatre which includes puppet shows, circus arts, classical plays and carnivals. We can spend all day watching different performances and shows.
I hope you'll like my ideas. If not, we can think about what to do when you come here. I'm looking forward to your reply.
Can't wait to see you in July.
Tim
