My Grill Communicates With Me In the Only Way It Knows How

I assumed that the very high temperatures on my Ducane grill thermometer were like the zone beyond the 85 mph mark on my mini-van's speedometer-- just for show-- but apparently, if you let enough fat and grease and meat shards pile up on the heat plates and the floor of the grill, and then throw a bunch of burgers on and close the lid, you can start a 700-degree fire inside your grill -- which charcoalizes burgers in mere minutes (and inspired me to finally clean the grill).
