(plaintiff, a horseback-riding instructor, entered into a contract with defendants to board her two horses at defendants' stables; one of plaintiff's horses died in a fire at the stables, and plaintiff filed an action against defendant, seeking damages for, inter alia, breach of contract and gross negligence; the trial court entered summary judgment against plaintiff, and she appealed; in affirming the trial court’s judgment, the court found that "gross negligence" involves conduct so reckless that it demonstrates a substantial lack of concern with regard to whether an injury will result; the court found that there was simply no genuine issue of material fact regarding whether defendants acted with gross negligence or wanton and willful misconduct; defendants took quick action upon discovering the fire and saved many of the horses).
