I had horses all through out my school years.
I don't know that they really interfered with my school work, and they sure gave me something to look foward to everyday after school, and after homework was done.
I was responsible for all of the care of my horse-minus vet care. I cleaned the stall as soon as I got home, and rode after I did my homework, or atleast most of it; however, I did most of my work in studyhall all the time, so I rarely had any homework, which was nice!
