The photo is not high enough resolution for me to offer you an identification of this gastropod. The only slug in our area that grows to that length, is the Leopard Slug (Limax maximus). They are not native to North America. You can read more about them in this bulletin from the US Fish and Wildlife Service: https://www.fs.usda.gov/Internet/FSE_DOCUMENTS/fseprd530663.pdf
