The other day, I went to Jackson Park with my friend Salem. I biked for two and a half hours at Jackson Park; it is this really cool bmx/dirt jump track about a twenty-minute drive from my house. When we got there, we started to bike on a small set of jumps on the right hand track. Once we warmed up we hit the medium size jumps. They are the same height as the far left ones, but the far left has a wider gap. Someone had messed with the lips so it launched you straight up. The highest I got was about four and a half feet off the lip (my wheels got that high)! While we were biking, this old man came and Salem asked what he was doing. He said he was the landscaper and looking at where to put in some trees so there is shade. In the summer it is unbearable without shade! After he left, some guy pulled up with loads of bikes. After about five minutes there was a mob of little kids there biking. There was this one kid in overalls biking the wrong way on the track which I thought was funny!
