Ryan Scott Miller goes all out to build elaborate wheelchair costumes for his son. He uses the mobility of the wheelchair in the costume design and ensures his son is beyond prepared for Halloween. This year Jeremy gets to be a Ghostbuster driving around the Ecto-1, which of course has light and sound effects. The complex builds often include extending material out and beyond the wheelchair. For the Ecto-1, he constructed a frame from lightweight PVC piping. You can see a couple of in-progress photos below.
