While I don't tend to agree with round penning the way most seem to do it, agree with Yadlim - you either got it or you don't. If there are no distractions, the only 'good' place is beside the handler, then whoop-de-do about 'joining up' IMO - no big deal, doesn't prove anything.
Getting your horse to *want* to be with you in the face of distractions & when not trapped in a small yard & effectively given no choice, teach you to be more effective & *truly* learn how to 'join up'.
...& Joe, should we direct the authorities to you next time we hear of any wild fires in your neck of the woods??
