Take your megaphone/loud speaker and wire it up on your property within 10 feet of the property line and start "preaching" with all your might, give a real good come to Jesus sermon and do it as often as is necessary to bring this man around. He needs to hear about Jesus NOW and to hear it as loud as you can make it and as often as you can make it. Make sure your neighbors know that you've turned to preaching so they won't turn you in.
The people of the United States are the rightful masters of both Congress and the Courts, not to overthrow the Constitution, but to overthrow the men who pervert the Constitution. Abraham Lincoln, 1859
