Hi, I’m Nikki, and I’m a scout! The Scout Association is a popular club for boys and girls. There are nearly 4000,000 scouts in the USA, and more than 400,000 scouts in the UK. Around 20,700 of those are girls.
This weekend, my scout group is going to go to the Scottish mountains. We aren’t going to stay in a hotel! The teachers have got small tents, but my tent is large – six scouts are going to sleep in it! It rains a lot of time in the mountains, and it’s sometimes stormy there, too, but I hope it will be sunny this weekend!
