In this video, Robert Madsen, president of Canada-based U-Lock Mini Storage Group and a director of the Canadian Self Storage Association, takes the ice-bucket challenge. The activity, which involves dumping a bucket of ice water on yourself or someone else, is designed to promote awareness and raise funds for amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig’s disease. To date, more than $100 million has been raised through the challenge.
