Want to play along?
Sketch by Jen del Muro http://iheart2stamp.com/ I've never been a guy aged 15 to 21 but I have been in that age group. In my memory it was a time of feeling grown up and wishing everyone else would treat me that way. Of course in time I discovered a few of the down sides (can we say taxes & power bills?) to actually being an adult but that isn't what this is about. This is about making cards for the guys.
Our first prompt is "Western Swing" Make a card focusing on the west. Cowboys, deserts, high mountains, First Nations/Native Americans. Kraft card stock, maybe Distress inks. This is just a jumping off place so don't feel constrained if you get an idea that wasn't spelled out.
