thats a fair comment. ther's lots of safty problems with teathering like:
*the rope snaping causing you to float off or the kite to luff and you to fall
*the kite ripping of the lines snaping which will cause you to get catapulted into the ground.
* the people or object you are teatherd to are also in danger as they can be easily lifted up and carried along
*as you are floating it is very easy to end up upsidedown, this can cause lots of problems such as landing on your head and breaking bones, dissorientation which can endanger everyone.
*gusts can cause a big problem too as you are floating you can get pulled to a great hight and then dropped.
there i think that probably covers most of them. say if you think theres others
