Dear Mum and Dad,

     Well, here I am in Peru on our South American tour. We got to Lima five days ago. We had a good

journey. It took three days by bus, but we saw lots of things on the way. We didn't do much for the first

two days, as a couple of other guys were ill. We spent most of the time on the beach. (They're OK now!)

On Wednesday we came up to the mountains, and yesterday we went to the old Inca city of Machu

Picchu and did some sightseeing. It was wonderful! We didn't have a lot of time there, but we saw

everything and I took lots of photos. And we're off to Bolivia tomorrow!

      Hope you're well. Did you get my card from Colombia? 

                                                                                                                                                   Love

                                                                                                                                                   Matt
