Personally meet with a legislator to communicate your position.
Most legislators have office hours in their home districts.
Do not be overly concerned if you end of meeting or speaking with staff rather than the legislator. In many cases, this is equally or even more effective. Be sure to treat staff with the same degree of respect you would afford the legislator. It is best to visit with legislators in a small group, three constituents is optimum, and to keep the visit as brief as possible. One person should lead off as the prearranged spokesperson.
