We love the idea of the vintage looking national park posters. I also want to incorporate 'Road Trip' in it, since it's a road trip through our national parks. The whole point is so people can come to the event and reflect on their favorite road trips. I attached another image that says 'Road Trip: Destination DAC'...but the image is only attached for a verbiage idea, not for the look of it. 

I don't want the flyer to look TOO old and western though. Bold colors, but still keeping the catchy look of these famous posters. I want people to relate to them. 

Please let me know if you need some more direction. Thanks for sending those ideas. As you can see, I used some of them!
