I also enjoyed the line the rainmaker used "I'm the seventh son of the seventh son...on both sides of the family! Hey, buddy, that's a pretty difficult thing...THINK ABOUT IT!" And I enjoyed the way the rainmaker ended his huckster speech after the rain shower by saying "Folks for $100 I'll give you a ground soaking rainstorm...for $50, a light shower...and, mister, for fifty cents, you can watch my mule slobber!" It seems I read a response to a thread on sdcfans that the reason the park officials gave for discontinuing rain maker shows is that the guy who played the original rainmaker, a long time employee, passed away, and they stopped the shows essentially in his honor, as even though many played the rain maker role, none could approach the mastering of the part by the original guy who did it. See an official SDC picture of the rainmaker at my Flickr site:
