I agree with Peter. I don't see a downside to applying to DYS. You have the opportunity to attend the Summit and/or one of the Davidson camps, and there are most likely regional events that you would be able to attend even if a trip to Reno doesn't fit in your budget. Just because the school is working with you and you are getting fabulous services now doesn't mean that you will get them forever, too. Even if his school district looks great "all the way up" right now, budgets change, and you guys could move to a less accommodating district. Being already a DYS member could help.
