The
Trip of Lifetime

This summer holiday, my friend Irvin and I
wanted to do something different. Instead of wasting our time staying at
home watching TV and playing computer games as usual, we decided to go camping(0).

After getting permission from our parents, we
began planning our trip. We made a list of all the food and
supplies we would need and spent an entire afternoon searching for the best
place to buy our camping equipment. In the end, our tent,
stove and sleeping bags cost a lot of money, but it was worth it.

When the day finally arrived, my Uncle Bob was kind
enough to drive us to the campsite after he got off work. We knew it would take
us a couple of hours to get there and Irvin and I grew more and more excited as
we got closer to where we were going. It was dark by the time we arrived, but
we didn't care. We waved happily at Uncle Bob as he drove
away. Then, after a bit of trouble and a lot of laughter, Irvin and I set up the tent and lit the cooking stove. As we sat having our first meal at
the camp - tinned spaghetti - we both agreed it was the best food
we had ever eaten. A short time later, warm and comfortable in our sleeping bags, we quickly fell asleep and dreamed about what our great
adventure would bring.
