Hello Sandy,

We have just returned form our holiday. We went with our friends,Edward Smith and his wife Tina, to the Yorkshire Moors. It is a beautiful natural park. There are lots of places to walk on the tops of the hills,miles of grassland with no people,just sheep and birds.

Edward had just come out of hospital and he could not walk as far as before. However, this meant that we walked in the mornings, and then stopped at a restaurant for lunch each day before returning to the place we lived in. Edward and I slept in front of the fire all afternoon, while the ladies went for another walk. Very pleasant!

I took lots of photos from the place we lived in, across the valley (山谷)below us, of the morning sunrise, and the mist(迷雾)in the valley. Also, in England, the old steam-powered trains are very popular. I took many photos of the train.

Yesterday we had the first snow of this winter. It is very early. We usually have snow in January. It rained all day, then snowed in the evening .Today we have bright sunshine! Both Jenny and I are well. I don’t know if I told you, in the last e-mail , that Jenny is now working in a hotel. Although she has to work hard, people there are nice, and she is enjoying the work.

Please write to us to tell us your news.

Yours,                                                                  Victor
