Well I don't board , nor am I fortunate enough to have my horses at my doorstep, but they are about 10 min drive away on some land owned by a friend, and another section owned by reletives. They are checked every day. If im away or can't make it I will get someone else to do so for me.
I am one of the lucky ones who has thier horses on thier property, but even then, because of my work schedule, I can't see them as often as I would like. I usually only get to the barn about three times a week or less. I feel awful about it.
I have them right outside and I "see" them several times a day. Because life is hectic I don't interact with them except maybe 4-5 times a week, less if weather is bad. I feed/water them check health and wellness everyday, but I don't get time to love them everyday. :(
