Really, what time should we be over?
I would suggest you get a brand new Weed Sprayer.
Then get some Peanut Oil, a large Jar.
Spray the inside & the grates lightly with the oil.
I would start with some regular Charcoal, just a bit, get the temp to about 200 or so, leave it there for about half an hour, then throw on some lump and wood and get it up to 350 - 400. Leave it there for about an hour, actually, at that point, you can just let it burn out. You should be good to go..
Call me when you are doing it, or if I can, I will try to stop by, PM me your address if you want.
Have a safe trip. Can't wait to see it out at Pulte.. Congrats..
