Dear Jack,
Thank you for your letter. Sorry for my late answer, I was preparing for the exam. You wrote that your class visited the British Museum. Unfortunately, I have no the opportunity to travel now. Our class almost does not attend museums, but instead, we go to universities on Sundays. The Pushkin Museum is my favorite museum. I have been there many times and it was amazing. I think everybody must respect its culture. While visiting museums, we learn something new, not only about the history, but also about other countries.
It's great that you and your family have plans.
How will you get? How long will you go hiking? What do you take with you?
