Color of Autumn

Several years ago, I went to park to see the color of Autumn, the red, yellow, green leaves of different trees. It was so enjoyable. I took a lot of pictures with the leaves as a background. I have not been in a park to particularly see the scene of Autumn for several years.
This morning, a friend called me if I would like to go out to see the color of leaves.  I said that I happy to go. So we drove for about 1 hour to a state park. I did not visit this park before. My friend visited this park several times. It is a famous place to visit. In summer times, people can come for drifting, camping; skiing in Winter time.
While I was driving, I asked Amy to see the beutiful colors along the road. I could not take picture because I do not have a free hand. The scene is beutiful. I have not seen this scene, this color for a  while.
We visited the park information center after we arrived at the park. I asked what activity it has today. The lady there is very nice. She explained to me about the activities year around. She also explained to me about the bike riding. There are a lot people coming to this park for bike riding. There is a place for bike renting. However, we did not  prepared for biking today. She told me that the bike trail here directly connected to the city I live. I thought this would be very interesting. I could ride a bike with Sarah to the park. However, Amy is too little for the bike.
We walked along the river for an hour. Amy was playing with friend's daughter. My friend picked several small oak trees for his yard. Amy said he was picking up Christmas trees. We saw the rich color of the autumn. I and Amy counted the number of colors. She could do much better than me. Although I am not color-blind, I could not describe colors and give the color particular names.
