This weekend I went mountain biking at Mission Trials Park with my dad and his friend, Steve. The weather was perfect, not too cold and not too hot it was perfect weather. There were a lot of hills, which were steep and slippery and made of gravel so it was hard to ride on them. You could see a long way from the top of the hill. You could see Mexico, the ocean and the freeway. It was very pretty! The biking was both fun and hard and I hope to go again.
