I use the Coyote Skates during winter time, when it's to cold in the water (I don't own a drysut yet).
It works really well and you can go very fast even jump but be aware, the grassfield is much harder then water. Just one advice, remove the brake system because it's get filled with dirt and the kite is much more effective
I don't go kiting on backyards or golf driving ranges so I watch out for freshly mowed fields and when there is a farmer around I ask!
Enjoy flying but safe
