"STANDING" IN COURT AND NEPA - WHAT DOES IT MEAN?
To have a seat at the landuse table when the big decisions are made about your trails, roads and riding areas, you must have "standing" in the NEPA process (and subsequent, if any, legal battles). You as an individual off-roader, are best usually represented by an organization such as your state association, national group or large umbrealla national group --the BlueRibbon Coalition
You must show up and sign in to public meetings.
Your name needs to show up on documents and official paperwork.
You have to show that you (and/or your sport) have been "harmed."
You do that with a very specific process (along with help from your local, state and national off-road groups).
