Just wanted to pass on two links that might be good resources for you all. Obviously, we are not the only Main Street program in Pennsylvania, or even the country for that matter. These two links should be helpful as they provide information on the Main Street program as well as links to other very valuable resources for anyone involved in a Main Street effort.
First, there's the website for the Pennsylvania Downtown Center. They are the group that is contracted by the Pennsylvania Department of Community & Economic Development (DCED) to administer the Main Street Program.
Second, there is the National Trust Main Street Center. This is the nation-wide version of the PDC and they have a lot of information on Main Street programs throughout America.
