so i smoked a round roast ,a pork shoulder,dutchs beans and all is great.we are all at the table eating when i see something out of the corner of my eye...the ecb i am smoking on is now engulfed in flames.....i never expected this and i dont know how it happened but it did.....i grabbed the water hose and put out the fire but i still dont know why it started,,,,maybe grease from the pork,i am confused,,,but we can laugh about it now since no body was hurt
