Dan, in the past I have provided support for the Nevada Northern via emails to selected Nevada legislators (who seem to understand that even though I am a California voter I am also a "contributor" to the Nevada economy). Emails seemed to be effective both in terms of getting what appeared to be "real" responses from "real" staff members, and the results. I know some folks argue snail mail is the best way, but you might consider listing email addresses as well. If I remember correctly the legislature seemed to have a pretty well set up email system. I seem to remember a tally of emails for and against various issues covering all the legislators, like maybe they pay attention if not to the individual emails but perhaps to the totals.
