Seems like a good ride, Failbhe! :) I would have enjoyed one like this. They always teach so many things both to the horse and the rider! And I cannot be scared away from a ride because of a bit of rain.
Last time I was riding Snickers, I decided to hop on him bareback in our way from the pastures, because the herd was grazing in the fartherst field, which is in about 35 minutes of walking distance. He was clearly remembering the Arab blood he has in himself in some ump-teen generation, so he wanted to do fast trotting, but was still negotiable to walk (asking for a canter, too, but I refused), was very spunky, spooked from a neighbor doog (that is one horrible pooch who likes jumping at horses' legs from an ambush), then spooked from a bird, but all of this was easy to sit through. Then, when we were really close to home, he made the grandest spook EVER, I had never experienced anything like this on him and I didn't see a reason, too - well, but something sure did frighten him! He started spinning furiously at canter, then tried darting through some thick bushes and trees, and then hopped on the road again and wanted to bolt back to the pastures, however, I managed to keep my calm, ease him down, point to home again and walk the rest of the distance in a somewhat relaxed manner. Would I want this to repeat? No. But I sure enjoyed the fact that I can sit through such major spooks even bareback and be leading enough to assure my horse he's safe with me if our continue our track - that was also a huge confidence booster for me. :)
I have come a long way, to surrender my shadow to the shadow of my horse.
