The Accessibility Summit is a conference held in the Tysons Corner area of Northern Virginia at McLean Bible Church. I attended it for the first time last year and I highly recommend it for anyone who wants to hear and be around those who look at the positive side of living with a disability and is interested in helping to integrate his/her self, his/her child, student, or client with special needs into all facets of everyday living.
Attendees can go to anywhere from 3 to 5 workshops (the pre- and post-conference workshops cost extra, 3 are included in the cost of attending) and they are categorized into family/caregiver, faith-based, and professional. A pre-conference and regular workshop are held on Friday afternoon/evening and two workshops plus the post-conference workshop are held on a Saturday.
One of the keynote speakers last year was Temple Grandin and one of this year's is her mom, Eustacia Cutler. If you are within a day's drive of Northern Virginia and the conference appeals to you, this is something worth attending! (From what I have heard, attendees come from all over the county. Washington D.C. isn't too far away, so some people attach a trip there onto attending the conference.)
