Doug, I would like to create a Facebook page for the 375th. It will be yet another way to publicize the events and especially the volunteer meetings to Portsmouth Residents. Just something basic to get it started and then with committee input it can include calendar of events, sponsorship notifications, pictures of the events and so much more.
I also spoke to Frankie Flowers the President of the ERI-4H. He is interested in hearing more about the 375th and how 4H can become involved.
A recommendation from someone that works at the Middle School is to inform the Superintenant (which I know you did), music teachers at all schools especially the HS, art teachers at all schools, and the history teachers as well. I would be willing to create a flyer that highlights the intentions of the committee for events but I believe we should also include some historical content that the teachers would be able to create a curriculum around.
A flyer would not cost anything except the printing costs and could be used to distribute to all business, organization and individuals in town. A flyer (formated as a jpeg or PDF) could also be distributed via email.
I happy to help just let me know!
