As far as metaphors go, this one doesn't clear the fence. I guess he was inspired by the Mississippi river, and the proximity to Hannibal. Maybe because he seems to be having so much fun, although that would make him more of a Tom Sawyer. If Huck played baseball, I can't see him as a power hitter. Maybe a reliever. I can't picture him playing baseball at all, although I can see Twain in the announcer's booth. Terry Ballard
