Jenn at the Keep Pride Rally

Welcome Community friends,

We are gathered here today to keep PRIDE in Port Jefferson Station.  We LOVE our Community!  Our community has so many wonderful things to offer and the best local businesses around.

We can not let bad publicity of our local area lower our expectations of where we live, work, shop, and play! We as a community are better than that.

The local business in this area and shopping center are hurting. They need the support of the community! Even though some of you choose to not shop here any longer, these wonderful local businesses still donate their time, money, and goods to our schools, churches and other organizations that we belong to. Think about that!

The small business is the back bone in every community and when an area within is threatening their livelihood, we the community need to say that we will not let that happen. Let our Voices be heard and our Presence be known that this community will be here to support our local businesses,  no matter what!
