There is a horse at the barn i ride at who has been nameless or many weeks.?

there is a black mare at the barn i ride at and she has been nameless for many weeks now. She is black and has a white splotch/stripe on her neck and one on her butt. She has a wavy tail and the splotch/stripe on her neck also goes into her mane. she is fearless. Literately! We haven't found one thing that she won't do! Sorry I don't have a picture of her but she is sorta new at the barn!
