I used to, BK (Before Kids). I rode up until month 5 of my pregnancy, but stopped as I didn't feel my skills were quite what they should be in order to ride while PG. I took it up after that child was born, and when I became pregnant again in a year, I decided to sell my horse ($$ and time concerns, as I was working f/t and taking call every third week). I do miss it. I rode a liver chestnut appy, took English (dressage) lessons, and rode trail as well. He was an "honest" 15 1/2 hands and had nice, solid hooves (good for riding here, which has lots of rocks). Keeping a horse and riding was a LOT of work but VERY enjoyable. Where we live is a good place to have horses, too, as one can pretty much ride year-round, just adjusting the times of riding according to the temps/light. We didn't have an enclosed, lit arena, but two of the arenas were lit. Dressage ring wasn't.
Freak?? Nah. Love the smells of hay, horses, leather . . .
