This is a middle-grade book that I read over and over in the early 70s. Here’s what I remember about it: –It was about a group of 4 boys who had adventures in their small town. –One of the boys had a wealthy grandmother and they used to go to her house for cucumber sandwiches (which one boy didn’t like because they gave him gas) –They heard the phrase “paint the town red” and went out one night, broke into the hardware store, stole paint, and literally painted the town red –One of the boys’ moms wanted to visit Schenectady because she liked the way it sounded. This makes me think that it was set in NY.
