Today, it's very windy, and there are gusts of around 25-30 mph. I've had both vents wide open for 30 minutes and the temp is stuck at 250. I thought more air equalled higher temps? Is this common, or is it more likely the small pieces and shake I filled to the top of the firebox, since i'm only cooking chicken tonight and don't need a long fire? I'm hungry and want this fire to take off. Any suggestions?
