I usually ride alone, because there isnt alot of horsie friends I can ride with that are close to me.
I don't carry anything with me lol, but I usually am riding in the same area, my back yard ( I live on 34.5 acres, and im usually on the same trail ) or in the hay field next door when it is empty.
I've had one accident with were I was riding down a gravel road, with pepper the very unbroke, green horse who did pretty good. But her trot is very bouncy and the saddle cinch broke, my right stirrup, and we were galloping, so off I fell and she was running off because the saddle was draggin on the ground, and I was chasing her amile. So I got to walk avery long time, ALOT of mile's picking up the saddle every now and again which I put on her back, and the wind kept blowing it over to bring it home. It was a crap saddle but I managed to pull a few people over to use the cellphone and my dad came and found me.
That very day, I had to ride home again with pepper on the highway. Glad she doesnt spook with cars lol and we had a dog chase us, not get home till midnight because coyote's were out and I was freaking out and I got someone to pull over and get their trailer !
Ugh, that was a heck of a day and I hope I never have to go through it again lol.
Sorry for the novel :)
