A few years ago, the PDGA created a video aimed at helping TDs with getting sponsors. It runs about 3 1/2 minutes and you can see the YouTube version on Brian Graham's "Bag" here
I had a version on my other laptop that I used to show people on airplanes. I think that you could get a copy from the PDGA, but I am not sure who to ask. It was very nice and the best way I had, during a flight, to show someone what disc golf us.
The YouTube version should work well anywhere you have Internet access.
Maybe it Brian see this he'll reply to this thread and attach the video to his reply?
