I guess the main thing is I got my trainer friend all worried about me

I was in an area with no fences and along our road which is a semi busy road with grain trucks and such going by.
She's right, I need to stay in areas where if I did get dumped I wouldn't be putting my horse in danger if she ran off. We just did our fenced in pasture today. I'll stick with that for a few more rides.
ETA I want to add, I really appreciate all of your encouragement more than you know.
