Minnesota has a very active Miniature horse club (they used to have a website but I'm unable to find it). But you could try contacting the person listed here: http://www.shetlandminiature.com/member-services/aspc-a-amhr-clubs/item/minnesota-miniature-horse-club.html Or they have a facebook page at https://www.facebook.com/pages/MN-Miniature-Horse-Club/259321917536523 - they used to put on seminars on basic care, fitting, showing, driving, etc. Lots of very knowledgeable people in that club.
