Flan in Rockford Files - addresses to write to

There are twitter things and email things and I think most interested people probably know about those because I've seen them everywhere - but if you want to do a writing thing, here's a lj comment with some addresses to contact (as well as an example letter).  I know in areas like political petitions one letter carries the weight of multiple emails or phone calls.  Not sure if that'd be true here, but I thought I'd just pass the info along.
