Go to the
White House Drug Policy web site. On the right side of the homepage, under Programs, click "HIDTA." That take you to a U.S. map with the measles. Click any red dot(s) close to your location(s); e.g. the North Texas HIDTA includes part of Oklahoma.
I'm sending you to the web site rather than just the map, because it's a great resource. Banks that must factor in proximity to a HIDTA should know what specific drug problems are found in their area in order to recognize symptoms in financial transactions. There is a ton of information here.
