Over the past 10 years, her one-room outfit has expanded to five studios in three locations and an annual recital showcasing more than 150 dancers of all ages. With each lesson, she teaches her students to exude confidence through their toes as they tickle the floor with an eclectic blend of ballet, hip-hop, and tap steps. Her curriculum aims to increase self-confidence, foster the development of new friendships, and improve fitness in students at any level or age.

At Fairtree Golf Centre, links-lovers hone long-games on a 300-yard driving range and short-games on a two-acre practice area. After grabbing their buckets of Pinnacle range balls, which the staff replaces each season, golfers toe up to one of 50 fibre mats that look out upon the range's expanse. Thwacking through a large bucket typically takes about 45 minutes, although some may opt to save a little ball ammo for the short-game area's two putting greens and arduous sand traps. Since there is no time limit on either of the facilities, players can take their time and recite a farewell haiku to each and every ball.
