Congrats. I love my Weber. I started with an offset Brinkmann and had to fuss and toil to maintain temps. A buddy of mine brough his Weber on a fishing trip and I was floored by how it runs. Practically light it, tweek it to set it, and forget it! After cooking the ribs for about 4 hours, that thing purred along at 225 for another three hours without being touched. I bought mine the next week! My longest cook was a 13.5 hour overnight brisket. On a warm, windless night, I poured about 1.25 bags of Kingsford in, lit one chimney and poured it in. Had the water pan full and tweaked a little to reach 225. I put the briket on at 11:30 pm then checked it every three hours, the only thing I had to do was put in a little more water. That thing ran at 225 for 11.5 hours, afther that I had to stir the coals a little and that was it. Looking forward to hearing about your first cook.
