I love the idea of attachments to the list!!! Wow our list owners must really love us! You can learn so much from pictures and diagrams! Some of us just don't always "get it" from a written explanation. I am definitely interested in more info on the unicorn attachment process and problems/advantages of driving it. I would like to give it a try soon but have to get new pairs harness first and need to know what extras to look for so I'll be ready. Unicorn does look really cool, too! I would also like input into how it compares with driving 4-in-hand. I've heard that unicorn is harder. Milli All Magnolia, Texas
