Good article and to the point
As far as a sound animal the agility topic pretty much covers that.
I have always had to complete training while on the trail.
No luxury items like an arena or riding ring.
Miles and "been there done that" brings em around.
Just did a second read of the article, really liked it!
I would like to add something but not sure how to put it.
Time is the topic of interest, expectations of the rider are not met quick enough.
Some of these things take time, not resolved in a few short rides
Or even in one riding season.
At one time a horse trader/seller I know saw me with a new horse(5 year old).
He said he liked the horse but it would take about three years till we really had it together.
I think he was right, don't get me wrong I enjoyed this horse from day one.
Great rides, headstrong, forward, and extremely agile but to harness this energy and for
Us to always work as one took three riding seasons.
Although you did state "Are you willing to put the same time and effort into your trail horse? "
Maybe I should say some people don't realize the amount of time, miles and
Patience that are required.
