Riding Sunday

My mare may be the perfect trail horse, other than being a mare.  We rode for about 2 hours Sunday and she was darn close to perfect.  She did what ever I asked but still paid attention to our surroundings and made good decisions. Me, not so much.  I let her run up a tall and less than smooth hill after the grand daughter and her horse.  I almost made it all the way.  Right at the top I lost balance and hit the ground, rather hard ground.  I was stunned a bit.  I'm still sore now.
