That's a great Father's Day present! Nice bit of cruising. I look forward to my kids to be big enough and have enough patience to undertake such a mission!
You are very daring rigging that close to a children's swing. If you did that over here in Perth, Cottesloe Council would have had an huge debate, dug up the swing, created windsurfing, Kiting and non-Kiting zones, erected signs and launched a public awareness campaign!!
I must say, it is probably for the best of all water users but could be argued, all this effort was initiated by someone rigging near a children's swing!!
