Coyote Hill Reginal Park trip

During the summer I went to many places. One place was Coyote Hills. We went biking with the Zhao family. First we rode into the entrance. When we got in we rode to a wooden bridge. We went on the bridge and rode till there was no more trail[There was water].Then we went to Dairy Glen trail,or was it called something else?I don't remember, anyways, then we rode onto a hill, but we stopped after a while because it smelled bad[There was sewage water]. Then we went on another trail till we got to a really steep hill. On the way back we saw an Alumni v.s. 'in school" race. It was cool. Finally we went home.
