Rhonda, as you know my 2 boys have Asperger's... so I can relate.The swing sounds awesome, and Zach looks like he enjoys it and is making good use out of it.
I think Kyle would have gotten some use out of something like that... but when he was that age he was undiagnosised and seriously misunderstood.
One thing you can tell Zach is that he gets to swing on his swing even when it's snowing outside and everyone else has to wait until it gets nice out!!!
