Welcome, Spence! Sounds like you're definitely on the right track. Lots of good smokes ahead of you! As for my 2-cents on the Pam issue: I use it, and find the grills scrub clean with just a little hot water and one of those nylon scour pads. Another spray I found that works better is Weber grill spray. It's hard to find sometimes in my area, but it handles higher temps better than Pam. I've also rubbed the grates with a little olive oil, too! I'm into easy clean-up! ;D
Throw some pics up of your cooks, if you can - we love pictures! Mmmm, mmmm!
