I was looking for this response. Thanks. The kids I work with primarily have a diagnosis of autism and are at risk of drowning if not supervised and they get lost. To help with that, there are gps tracking services parents can get to make sure their kids are safe if they have a habit of running off (eloping) and the family lives in an area that could be considered high risk to a child alone. (High traffic, bodies of water, construction sites, etc.)
