O.K. Let's start you off with a video that kinda sums it up. It's titled "Old Rhinebeck Aerodrome Tribute".
I like this because it showcases Cole Palen's 'Flying Museum' out in Rhinebeck NY.
About 35 seconds into the video, Scott MacKenzie describes flying in the vintage airplanes - his statement really captures it well.
Note: As you watch the airplanes flying and landing, notice the trees in the background. These guys fly in some wind!
There's a second video here that shows more flying and fun at Old Rhinebeck.
The third video is a brief history of Bernard Pietenpol's home-built design - by Grant MacLaren
Here are some pictures I have collected from some Dawn Patrols around Michigan:
