I usually BBQ year-round. I have friends who get the BBQ out at the end of May and store it back in the garage in September. I can't live without having BBQ that long.

I have a rack of baby-back ribs in the freezer waiting for me, in fact!
One of my favorite steak marinades is an Italian one I found in one of the Weber cookbooks. Uses 6 tbsp oil, 3 tbsp red wine vinegar, 1 tbsp balsamic vinegar, 1 crushed clove of garlic, 1 tsp. basil (although the original calls for rosemary which we don't care for), 1 tsp. Kosher salt and 1/2 tsp. ground black pepper. Six hours in a zip-lock bag and it's ready to go on the grill. I once had a neighbor across the street ask me what I was grilling that smelled so good.
