Volunteering With My Adult Son With Down Syndrome?

We have been camp hosts in parks since 2006. My wife's sister is a mentally disabled adult and has always been welcome and helpful.

We like the US Army Of Engineer parks as the volunteer hand book actually encourages family members to help.

We often ask the rangers if they have a boring repetitive task to be done, like stuffing 1000 envelopes, as my sister in law absolutely shines when completing those tasks. She loves it and the rangers love not having to do it.
