Feet matter. How many feet something is from something else is not arbitrary. It needs to be a workable doable number in a large number of cases, not just a few cases.

 The Wind Power Ordinance up for second reading in April in Frelinghuysenfolly, makes it illegal/against municipal law to place wind power within 1000 feet of a school.  That statement makes it impossible to place wind power on the Frelinghuysenfolly School grounds at all- because in every direction from the school, on school land, the school never has 1000 feet from itself on its land. No wind power for students to use in their curriculum, or in our municipal electric costs, on top of one of your most productive west facing hilltops.
