Visit the park; it's a peaceful, clean, and pleasant place. The trees are beautiful and it's well-protected. People often bring their lunch or coffee here and sit and chat for a while or simply relax.

Horrible experience, terrible customer service. I was told I cannot cancel my insurance policy due to the fact that my ex, listed as an occasional driver, hasn't signed off on the cancelation. I was charged the cancelation fee, then they continued to charge me monthly. AIG has been much more reliable.
