Dear Patron, Thank you for your contribution to the Sunset Maritime Museum. Our efforts to pass on our rich seacoast history to the next generation have been a phenomenal success. We were able to raise more than $60,000 this past year. There are many projects in progress and more planned for the following year. several retired sea captains have been volunteering their time for live 2. storytelling sessions, which have been getting young people interested in boating and fishing. Consequently, we hope to exceed the amount of donations this coming year. An anonymous donor has contributed $20,000 to get the ball --3--.We are delighted about this, as we anticipate remodeling costs of $100,000. We understand that everyone's resources are limited, --a- we ask that you help us spread the word by forwarding this to your family, friends and associates. The Sunset Maritime Museum is a worthy cause. Since the museum reopened, the number of people staying and working in this town after high school, as well as those attending college and coming back here to work in family businesses has increased almost 10%. Help save our local heritage. Your help willbe appreciated for generations to come. SVBd (8) 1. (A) Actually, there were at least a dozen new projects involving seabirds.
