We burned off our pasture early this year -- with low winds and the burn ban lifted, we didn't want to wait to see if we got a better day later. If you've never seen something like this in person, it is quite impressive. The tall mixed prairie went up and the fire roared across it in a matter of a few minutes (about five). Cedar trees are an extra bonus -- besides being a foe to the natural prairie by soaking up way more than their fair share of water and choking out native plants, they burn up hot and fast. I saw a fire ball about fifty feet high last year when a group of five went up at the same time (Murphy's law, no camera). Just in case you are wondering, I'm a bit of a fire bug.
