Young Girl On A Horse

I was on my balcony one fine day,
When I noticed the young girl's horse was grey,
And they were trotting gently on their way;
The girl was riding with a lot of style,
She must have ridden for a longish mile,
And she left me amused for quite a while;
'cause it's most unusual for one to see
Near a private gated community,
A young lass ride on horseback saddle-free.
