Dear CHRIS KLINTON,
Many thanks for helping out with the park tidy-up. Your hard work and continued effort did not go unnoticed and you inspired the other volunteers. It is not a coincidence that the park looks better than it ever has. Many thanks for being such a great neighbor and friend, your example will not be forgotten quickly.
