How does this whole thing work?
It's all about sparks of support, and the flyers are the sparks. To join - simply buy some flyers just like the one you received. Once you get them - keep 'em handy because it won't be long before you see someone awesome flying Old Glory. That's when you hang a OGFC invite-flyer on their door or mailbox. Do that repeatedly around your neighborhood, around town, or anywhere until you run out of flyers (then order more;). It's completely up to you on how to distribute them; you could even hang one on a car door handle.
The beauty of OGFC is you can be completely anonymous and quietly 'fly it forward', or you can knock on your neighbors door and give 'em a high five while hanging a flyer on their nose! Just keep flying it forward. Hopefully all those sparks will catch fire and others will then buy some flyers for themselves. The goal is to get that process to repeat until every person flying Old Glory worldwide has an OGFC sticker in the rear window of their car... On their toolbox... Their guitar case... Skateboard... Garage fridge... Cooler... Bike helmet... Red wagon... Forehead...
