Definitely Dysart’s truck stop (eat breakfast there) the standpipe, the barrens, the Pet Semetary cemetery, the Oriental Jade...
Also, get in touch with
Robert Gray ! They moved to Maine because they are Stephen King fans and have a gorgeously renovated church that is now a home with a viewing room! He’d be happy to give you the fifty cent tour for free. There is the Derry Public Works building but tread lightly because it’s now a rehab house if sorts. The residents get cranky. Visit Gerald Winters store but maybe rake out a second mortgage if you plan to purchase anything there. Love Gerald and the store but it’s wayyyyy out of my budget!
Robert can give you context on everything.
