Roger - I still don't know what a Parson's clip is. Maybe a picture on the web page would help? I mean I have an idea what it is and what it does, but a picture would tell the story.
I just linked that page from this page on my site. I will probably link it from other pages later. I can think of at least two other pages on my site where the link would be appropriate. A lot of "experienced" flyers would do well to read and head that article - especially the parts about safety and being prepared.
