recreational, only special equipment is a kite, you run and jump, really need high speed wind thou, you sould of tried it today, hopefully wind will be as strong tomorrow, forget your skates take some good trainers, best to try this on grass first tho, you land wrong and your ankles gone, but imagine jumping 7 mtrs high (my record) with nothing under you, amzing, plus it's possible to get better air as theres nthing weighing you down,
