Yup...people are afraid of this right up until the time they NEED help, and then they find they can't get it, because, technically, you don't exist (because you haven't reported).
An example of the connection between reporting and $. This doesn't involve NASS, but same idea.
Back in the Jan 1998 ice storm a huge number of maple producers were affected across a wide swath of the northeast (Quebec and Ontario were very badly hit). The Vermont Dept of Forests, Parks & Recreation did an absolutely wonderful detailed map of damage, with stand maps and classes of damage delineated very precisely across the entire state. Other surrounding states....not so much. They basically just took a wide marker and colored in half the state, a good deal of that was "scattered" or "light".

So we're thinking...great, at least in VT we have really good and useful info. We thought that right up until it came time to dole out the $ for research and damage clean-up. The U.S. Federal Government divvied up the money by acreage affected. So our great detailed VT damage map totaled a fairly small area compared to surrounding states, and we got less research and recover $ because of it. It would have been better in some ways if they'd used a wide-tip marker or crayon.
