Soup by Robert Newton Peck
This is the first book in a series about the adventures of Soup and Rob, two boys growing up in a small town in 1920s Vermont. Soup is always getting Rob into some kind of crazy trouble. The books are fun and Soup and Rob are good kids with good values, even though they get up to mischief. I also recommend the rest of the books in the series. Soup and Me is the second book.
