As I'm not in a HUGE essay mood, I'll give a little, and hope that someone else adds to it.
Dorothy Lundgren Lee was the Alpha Delta Pi who brought ADPi and Ronald McDonald House together on an International level. I can remember when Scott Paper products were involved also, and their ads always included someone wearing an ADPi t-shirt!
Little known fact: when the RMH's were first conceived, the original backers took a survey among children under 12 as to the most recognizable "cartoon character", thinking that Mickey Mouse would win. Nope, it was Ronald McDonald, which is why the houses bear his name!
I do know that RMH provide families of sick children with a place to stay while the child is being treated, but not the finer points.
NEXT!
