Trip plans are a great idea. However, the problem I see with the plan linked in the OP is that it is very long and complex. It might be OK for a planned expedition, but I suspect a lot of folks would not bother doing it for a short weekend trip. As an alternative, here is a link to one posted by the Alaska State Troopers:

I tend to be of the KISS mindset ("Keep It Simple, Stupid"). The short trip plan you actually fill out is infinitely superiour to the long one you meant to do...but never got around to because you were in a rush trying to get out the door!
