the perfect gift
Believe it or not, a gift voucher for Reuben's birthday was how the owners of Wings & Waves got into the sport some 30 years ago. A voucher for something to do which he / she may like or has spoken about, is just the perfect gift.
You don't need to wreck your brain too much as to which voucher to buy: You can exchange the voucher to any other course within the validity of the voucher. You can up-grade from a trial flight to a one day course, or switch to kitesurfing if you'd rather do that.
