An uphill battle is nothing new to Russell Rego, but the Hall County resident keeps pushing like the 21-year Marine veteran he is. When the U.S. Department of Veteran Affairs declined to declare him 100 percent disabled several years ago, he appealed the decision and won. And now, Rego, whose disability stems from his service years, is trying to change state law so that veterans can get a retroactive property tax break based on their lengthy wait to get full disability through the VA. He’s motivated by his own unsuccessful attempt to claim such a break earlier this year in Hall County.
