Jack: My only other suggestion would be to have them let you know when they plan on burning it so you or someone can be there to verify the height of the grass. I hate to harp on these guys, but we have two rather large fish and game areas up here that the DNR owns, and their 'experts' that do the controlled burning torched some tall grass a year ago in high winds and burned down their tool shed with all of their tractors and equipment in it. OK...I'm done complaining about the DNR... KDC
