We have a member of our ward who is in a wheelchair. We have him come to mutual and tell us how it happened and what it has been like to be in a wheelchair. Then after he is done talking we arrange to get two wheelchairs and set up an obstacle course in the cultural hall and let the girls navigate their way through it. It is fun and gives the girls a good dose of what it is like to be in a wheelchair.
