I am remembering a book I read in the mid-90s, when I was around 10 years old. It’s about a teenage boy who either lives in or moves to a small town in rural California (I feel like I remember there being a line about “there was a sign on the road out of town where it said Los Angeles 567 miles [or some large amount] and someone had crossed it out and written 1,000,000 and honestly it might as well have been.”) Someone in his community teaches him and the other youths how to “witch for water”, or use a dowsing rod, and nobody is successful except him. He can feel the water through the rod by a sensation in his wrists and arms. Later on, he feels the same sensation without the rod, and discovers that he is essentially a human lie detector. There is a scene where he goes to help a friend’s dad as a border patrol officer on a state line, and helps them to confiscate illegal fruit that can’t enter the state for some reason (a big carton of cherries in one case, and like two apples in another.) The fruit-at-the-border isn’t the main plot thrust, but it’s the part I remember!! Thanks for the help :):)
