Yep, that background's from an old colored-pencil drawing I did a while back. Trust me, I'm a lot better at drawing from real life than I am at drawing comics.
Just so no one gets the wrong idea from panel #2: To get me to remember to wear my seatbelt, when I was little, Mom turned it into a race to see who could get their seatbelt on first. That game abruptly ended when I was running to the car in a public place, shouting, "Don't beat me with the belt!" But I do always wear my seatbelt now.
I'm not a vegetarian, but when I found out how veal was made in middle school, I came home in tears. Poor Mom promised me she'd stop eating veal, even though I completely forgot about until recently.
