I Googled "BLT sandwich" and grabbed the most delicious-looking image result. Haven't changed it since.
Fun fact, within a day of me joining the forum, landbeforetimelover messaged me with a version of my avatar he'd given a transparent background so it looked nicer (before it'd been on a plain white background because I stole it from Stockphoto). I was really touched by his kindness, especially since I only had 1 post at the time and there was no promise I'd even stick around in the forum.
