Shoot at them?? Here in GA if someone comes onto your property uninvited you are legally able to shoot them. I kid you not. I went to a mounted patrol clinic and the guys from the police department (there officially and in uniform) told all of us to go get guns and help them out.

Somewhere - behind the rider you've become, the long hours in the saddle,
the ribbons you didn't win, the falls you've taken, the tears you've cried,
and the horses you've given your heart to - is the little girl who fell in love
with the sport and never looked back. Ride for her.
