Answer:
"It was full of skateboarders performing such impressive and daring maneuvers that I had a hard time tearing myself away to return to my bike ride. I now believe that the park will be a valuable source of entertainment and exercise for our town's skaters and that it's worth every dollar the town spent on it."
Step-by-step explanation:
This is by far the longest sentence and one that explains how much the park means to the author. "I had a hard time tearing myself away" explains the emotional connection the author has with the park. "I believe that the park will be a valuable source of entertainment and exercise" is the author trying to prove that the park is useful due to his/her connection to it.
