Mezza and I checked out our ground work without a hitch today (no mass exodus of pigeons either) and went on to do a ride in the heifer pen. I had hoped to follow up with hand walking her out in the open space along the canal again, but today she had the fence line calling her name, and we worked an hour at getting rid of that urge to stick to the back fence.
Here is a video of us trotting about. Sorry my camera doesn't track motion, so there are some 'empty' sections, since the pen is quite large! The video is a bit long, so I have to provide a link.
