Answer: Although you might be able to grow a tree from the peach pits, the tree will not be the same as the tree that produced the fruit you liked so much and the fruit will not be the same, either. Peach trees are usually grafted to assure consistent quality fruit. If you can find out what variety of peach you liked so much you could purchase the same variety of tree. Peaches are not reliably winter hardy in Maine, so I would suggest you work with your local county extension to determine if the variety you like is worth trying to grow, or not. (Reliance and Redhaven are probably the most common hardier varieties grown but based on your description of the flavor it may not be one of these, although a fresh peach ripened on the tree is going to taste pretty good no matter what the variety!) I'm sorry I can't be more encouraging.
