The house I grew up in had a storage room underneath the front porch. As a kid, I would pretend that I was trapped in there and that the door had no handle. I would feel along the hard unfinished concrete wall searching for a light switch. Every time I found it and flipped it on I would realize I wasn’t alone. My adventures changed each time I played this scenario. The room contained monsters, aliens, skeletons, vampires, bears – sometimes it would be my imaginary friends throwing me a surprise party. Twenty years later my characters, Lincoln and Stax, entered that same scenario. Bottom line is it’s best to draw or write from what you know or experiences you’ve had.
I also know a few friends who can stink up the place after taco night.
