Thanks for the input everyone, it would just be for a minute while I moved the horse so she can exercise, I'm not going do anything with my horse except watch her, there are picnic tables and a grassy area to do so. The stroller thing made me nervous, especially because my kids can get out of that. There is a car law in my state, although I saw somone lunging thier horse outside of the arena with maybe a 3 yr old running around loose by the horse and my heart dropped in my stomach, the kid easily could have gotten run over, it was scary. The barn I'm at is pretty relaxed, I don't see a problem with it and hopefully if my lesson guy is there he can give me a hand for a minute, but I don't want to depend on that. And btw I don't even leave my kids in the car the pay for gas!! Although everyone with kids I know does, which I don't see a problem with, I'm just paranoid lol!
