Instead of using conventional advertising techniques, we decided to approach people with the grass-roots method of simple, genuine conversation. We explained that our idea was to bring about positive and healthy change by taking short walks instead of riding the tube one or two stops. Most people were surprised at how much shorter the distance is from tube to tube than they had imagined. We're hoping word of our blog will be passed along, and in the future the congestion when riding the tube can be lessened. We know people will feel healthier and more positive after taking a walk instead.
