I really don't know what to call them -- 4 years ago when we went to Disney the CM in MK gave me a tag that was a Mickey head that I could write ds's name and contact info on to have on him if he wondered away. So, I realize that he's 4 years older now -- he does know our cell phone numbers -- but do they still give some kind of tag or should I consider coming up w/ some other type of id tag. We do have the MB -- it seems like I read they were trackable? or had the contact info in them? Maybe I'm just being paranoid that we'll lose him - although it's been known to happen in places much smaller than Disney.
