I always remember playing football in the back garden from a very young age. We had a small garden that had three tiers. The bottom tier was made of concrete patio stones and was probably around 12′ x 20′. Our neighbours fence would provide the goal and my brother and I would play simple games like first to score 5 goals. We’d have lots of fun until the ball went over the fence. It was a great motivator to keep the ball low.
