No matter if the photo is taken on the trail, before or after, as long as the horses and your own ''tack'' is clearly visible :) Would be fun to see what you all use and dress like, saddles, breastplates, bridles, bits, clothes etc :) If you want you can write what you ride in when you don't ride on the trail.
I'll put one up as soon as I've emptied my camera and found someone to take a picture .P
