Ride a mountain bike Yesterday, I found on google maps that there is a large green area just to the north of my apartment. My former roommate told me that to the north of downtown Toronto, there are many trails in the forest that are good for biking. (It's not a forest. It’s just a green area with a lot trees. It's called Cedarvale Park. What's the appropriate word?) So I decided to explore this area. I rode on my mountain bike and used my phone as a GPS to get to the entrance of the trail. When I got there, I found there was a set of steep stairs leading to the valley. I believe the trail is in the valley. So I carried my mountain bike on my shoulder and went down the stairs. When I reached the bottom, I found the trail was too narrow and steep for biking. The ground is so slippery that I almost slid down from the hillside. So I decided to return to the entrance. I think there must be a good biking trail nearby. I will find it next time. Biking in the woods is a really good exercise, and it protects my knee.
