Atli doesn't like indoor arenas either. He had two runaway Icelandic run into him while he was a youngster the same day.
One during a semi private lesson when the owner panicked which lead to a bolt. Another during a costume class when the "helmet" covered the riders eyes which lead to a bolt. Atli my green baby stood still both times and both times the horse ran right into him. Otherwise he is an incredible horse! Cheryl Icelandic Sheepdogs & Icelandic Horses www.sandcreekicelandics.com
