Saskia, you would be surprised on the height of the horses, the average is around 16hh! I used to play on a 16.3hh and once you get the hang of 'picking up' then height is not an issue! :) and the level of play doesn't go on the age, I play in England and for new starters there are 'Novice divisions' which means basically everyone is new and does everything at walk/trot.. odd canter! There are not so many Juniors (under 16's) who play anymore :( but a few years back they were the best ones to watch! (fastest, scariest games!)
RiverBelle .. I am intrigued on Donkey Basketball!!!!!
