Joe needs a fence for the yard fund

I am the mother of 2 autistic boys ages 6 and 8.  My oldest son Joe, is severely autistic.  Joe struggles with understanding the world around him, and can not engage in age appropriate play.  He is unable to engage in any typical activities due to his nonverbal and delayed developmental levels.  Joe does love the outdoors, and is always excited to go outside.  This is the one thing he  truly loves and is able to do without assistance ( as long as he is closely supervised).  Joe requires one on one  at all times or he will run off.  His running presents a great danger to himself.  He has a service dog to keep him safe when we are in the community.  I am asking for help in obtaining the funds to get Joe a fenced in yard.  A fence would ensure Joe's safety in his yard and allow him more freedom to play.  Thank you to all that reads this and feel they are able to help.  A fence would be life changing for Joe.
