Man, I wish we had a backyard, but my fiancee and I currently live in a 1-BR apartment. Even with a decent-sized balcony, we are not allowed to have grills there (unless it's an electric grill).
Someday, when we move to a new place, preferably a house (whether we rent or buy), we will definitely require a backyard for our dog to play in and for us to do outdoor cooking or host small outdoor events!
I live grilled onions on burgers, too! Every opportunity I can have them, I add them!
We went to a cousin's house yesterday. One of my cousin's hosted a baby shower for his pregnant wife!
We held the event at their backyard, and even though it was hot (summertime in Southern California), we still had a great time!
Someday, I'll do fun things in my own backyard. :)
Enjoy your time before it gets too cold over there, wherever you're at! ;)
