Before I attach pics I have to reduce them significantly to about 25% of original size. That seems to work but I only ever manage to post the thumbnail sizes. I don't have FB nor a proper phone so do it via my tablet.
This one was really for my barefoot FB group as we're b/f & did 11 miles of tracks, roadwork, the odd log & some v hard, stony tracks. The only difference between him & the shod horses I was riding with is that he didn't slip on a slippery bit of downhill road!
