That is a great idea Angelo, and I would love to get up there to attend.
I have a 4yo son with autism and one of my 2yo twin boys also has autism, my eldest in the high functioning spectrum and is quite normal just a little behind in a few areas, my other son has not been officially tested yet but looks to be a little worse unfortunately.  Both are beautiful boys and I feel lucky that they don't have more serious forms of autism, I could only imagine how overwhelmed your friends feel with a daughter with downs and autism.
Good luck with the fundrasing mate!
