Texas legislators have large egos . . . they like letters and keep a count of them but they tend to ignore those that seem to be identical and come from a "campaign". It is better to write a letter using your own words but delineating the things you want improved.
You can (if you have a computer) type in on your "search line" = "Texas Legislature" and the site will come up and you can retrieve the names of all of the TX legislators. The House of Representives has one Post Office Box address while the Senate has another. The same box for each category. LETTERS LETTERS LETTERS
Remember that strength comes from "numbers" and the more letters received by the legislators, the greater the chance for success in our endeavor for increased protection.
You might also consider writing to "Letters to the Editor" with your local Valley newspaper.
