Horse Back Riding

I have a friend in the Philippines who own a farm that offered me to visit their place. I have mentioned to her that we are going home for a vacation mid next year and she is excited for us to come to their place and meet my family for the first time. They have different farm animals and they have trained horses for back riding. She wants me to enjoy horse back riding free of charge. The offer is really tempting. I have not commit myself yet as I have so many plan activities to do when we go home for a vacation. But just in case I have enough time, I will definitely visit her and enjoy horse back riding. Even if I am not sure, I still want to buy some breeches that I can wear should I decide to go horse back riding with her.
