Well, nothing spectacular, I'm creating my own cards (in an envelope) to mail to these SOBs. I used to write lots of letters then got demoralized and then started writing again. No one writes much anymore, meaning real messages on real paper in real envelopes.
Time was when it was hard to just trash real letters to these people, they had to do something and the idea being that "processing", being handled by several people ("Here Suzie, send a form letter to this idiot"), it reached more folks that you imagine.
I learned this by being able to access a large state bureaucracy during my career, where all the moguls ruled from. It was said by a bureaucratic fatcat that each letter represented at least 10 people, probably closer to 100s, truth be known. I've seen a few letters actually change proposed laws, so it CAN work.
Good plan. Of course, my congress critters (my goodness, my state rep is Wexler!) are probably not going to care a whit what I think, but hey, I need to let them know!
