buzz--you may find the book "red clay, pink cadillacs, and white gold" of interest--it is about the kaolin industry and it's leases in middle georgia--granted the book is one sided but many good points in there--example you say after the towers are abandoned for "x" amount of time the land has to be restored--the same occured with some of the leases written about in this book but there were some legal ways around it. this is an interesting topic and you and others raised some good issues on both sides of this subject. a lot of things are necessary (dumps) and several may become necessary (wind turbines, etc) but the issue is tolerating them in your yard/neighborhood/area. IMHO it's sorta like the water tower mentioned before--- i think i could get used to one water tower/wind turbine maybe but looking at a whole series of them all the time would bother me (esp. at 2 to 3 times the size of a water tower).
