I agree with Tom on this that an ideal solution incorporates positive incentives, though I think it needs to also be coupled with negative measures for repeat offenders.
Negative measures for repeat offenders does seem like a pretty fair and reasonable solution, with less chance of harming people with legitimate reasons to cancel.
I also like DBKs' idea of more weighted lottery's and point systems.
I actually like a lot about the Grand Canyon lottery system, as much as I have bitched about many other aspects of how things seem to run in that national park.
Agreed that we should not castigate all regulatory agency's for the problems that do exist. If it sounds like I have in my posts, I apologize, though there is much that angers me in many areas of Government, there are many good people doing a good job to. Just can't help wanting the bad apples out of the bin, always feels like there are a lot.
Shutting up now and going boating.
