marad,

I agree with Mr. Hipson. Your pets are likely saddle ponies not draft
horses. Saddle horses are not bred or trained in this work. I suspect that
you lack much experience as a wagoneer and will lose interest as you look
into the expense involved in this project. If not you may wish to get some
mules. Why are horses terrified of bikes? Last time I was ahorse when bikes
came by I thought I was a dead man.
