I was doing Vortex Ribs on the river yesterday and at 50 minutes opened lid to sauce. A big grease fire started at the bottom. I clean the kettle good before putting back in truck so it was clean to start. Any way to prevent this in the future? Also I been pulling legs of to store. One got crushed. I was able to fix it enough to get part way in hole. I will try to get it back into shape. Think I will get some rubber caps to put over them in the future.
