We cook just about ANYTHING on the grill. We use the grill year-round, too, but admittedly less in the winter. Still, if we want to grill burgers or steaks, unless it's STORMING we won't let the weather stop us.
That being said, bring on summer and the honest-to-goodness grilling season!
(Potatoes in foil packets with onions and butter... mmmm)
