I've got an old-ish kite (liquid force Solo 9m V1) and a waist harness (Small Dakine, forget the model) sitting in my storage locker gathering dust.
Both have been moderately used (probably 70 hrs on each), but are perfectly usable. I could get maybe a couple of hundred bucks selling both second hand, but it doesn't really seem worth the hassle.
Is there any local donation scheme that could get them to someone / some organization that would appreciate them?
There's a kite camp for kids at the village at Nitinaht, I know they need gear for sure there for the locals who are learning. You could arrange to have the stuff dropped at the campsite with Pat or Kim if you know someone heading there before the end of the summer.
