Head office possibly exaggerates the wonders of power-kiting whilst on the phone selling the activities to schools. Most of the kids talk about it as if they're going to be strapped into a wheeled vehicle and yanked to Spain and back by a nylon Pteradactyl.
In reality, our Power Kiting is just Flying A Kite and eight times out of ten the wind is too strong or not strong enough. They should call it Beach Disappointment.
If the wind is right though, and the kites go in the air, you have to spend half your time making sure the kids don't slam the kite into Gerard Depardieu's collarbones and the other half untwisting the kite lines [never "strings"] after failed attempts to do so. Meanwhile the tide creeps up and the beach gets busy and the group gets restless because there's only two kites for usually about twenty kids.
Once, during no wind, we had a Beach Art Competition, and some of them drew a twenty-foot tall transgender robot called Roberta, and made the least tall kid sit in the middle where the genitals weren't and pose for photos. They won.
