The first thing you have to do is get it home safely. (I laughed and laughed when I heard this story). Apparently there is a vacant lot on the corner right next to the local WalMart. The employees at WalMart call this lot the Grill Eater Lot. There are several smashed up grills that ended up dumped in that vacant lot as their owners took the corner too fast and lost the grill out of the back of their pickup trucks (I totally need to drive over there and get a picture). So – a tip for the new grill owner – tie it down before you leave the store :-).
Brining or soaking the ears in water before grilling is thought to season and also plump the corn. There are two problems with those theories, though: In order to take on any salt from the brine, ears would have to soak for several days, at which point you’re losing valuable sweetness as the ears age. Secondly, if you’re buying fresh juicy corn, you cannot make it any juicier. While soaking may benefit older or off-season ears, it has no added value for fresh summer corn.
If you happen to be using an older Weber grill, or any other type of barbeque grill that wasn't coated with porcelain enamel, you'll need to season it before using it for the first time and sometimes reseason after seasonal storage. For example, when using a gas barbeque for the first time, always season it unless the directions specify not to. The procedure is the same for charcoal grills as for gas grills since it's the cast iron grates you're seasoning, not the gas or charcoal component.
Check the fuel lines for invisible openings. Create a mixture of soap and water. Make sure you stir the mixture around so it gets really sudsy. Then, use a paintbrush to brush the soapy mixture onto the fuel lines. Turn on the gas, and brush some more soapy water onto the gas lines. If any bubbles form on the gas lines, that indicates a gas leak. Immediately replace any fuel lines that exhibit signs of a gas leak.
