Saturday morning

Объяснение:

It is Saturday morning. The weather is awesome! It is warm and sunny.  

My friend and I are going to ride our bikes. Today, we will go mountain biking. We have set a new route that is intriguing.

My bike is green. My friend's bike is yellow. We will ride slowly today not to get lost.  

We will take some sandwiches and juice to get some food with us. We do not know when we come back home. Our parents are aware of our new route.
