A couple years ago I purchased the Larry Parnell video. It has some very good suggestions and pointers. However, there are other videos that might benefit you more at this point. Try searching the forum with the words "driving video" and I think you'll see some other good choices.
I have never seen any videos on driving instruction that I thought were worth the purchase price (Not that I have seen many) My advice would be to go to a few combined driving events. If there are people near you who drive ask them for help or at the very least to let you watch their training. driving is such a simple aspect of using a horse that it is entirely possible for a person with no background to do an acceptable job of training a horse to drive. Watch a little ask some questions and try it. Once again look to the search function of this forum and you will find a wealth of information.
It's funny that you should mention the video. I just watched today. I'm getting ready to start driving. I felt that it has a lot of good tips and instruction. Some teachings were a bit confusing. It's worth the money, considering some tapes cost 40.00. My big concern about driving is the bit issue. Good luck, Dionne
I did think the price was pretty reasonable. So I think the next time I send something in I will get the tape. At least I will have something to work on over the winter. If I watch it enough times maybe things will sink in.
I had someone at an AMHR show check his bit to make sure it was not pinching him.
At open shows everyone drives differently. Some smack the heck out of their horses and they just stand there and others jump all over the place. I haven't even tried touching my guy with the whip yet. I am afraid he would freak out. And I don't need that.
