Today I’m going to talk about tents. Camping is still one of the cheapest ways of having a holiday. And each year, over 3 million people take camping vocations, either here in Britain or abroad, mostly on the Continent. Obviously, camping can’t be as comfortable as living in a permanent house, but modern tents can be very comfortable indeed, with windows, bedrooms, kitchens and sitting rooms. The most popular tent sold in Britain is the frame tent with 2 bedrooms and sleeping accommodation for 4 people. There is usually an outer tent of water-proofed fabric and a lighter inner tent or tents with a built-in groundsheet. The outer tent fits over the frame work. This is made of metal poles which are fitted together. The inner tent is attached to this frame. Generally, the inner tent is about half the area of the outer tent. The other half of the outer tent is the living area. This doesn’t usually have a groundsheet but you can buy one to fit, though it costs extra. The ordinary 4 bed frame tent doesn’t usually have a separate kitchen area, but the larger ones often do. You can buy a kitchen extension for many tents, and it’s worth buying one if you plan to stay camping in one place for more than a few days.
