I live within about a mile or a little less from at least 4 cell towers. 
I've never heard a peep from them even driving by and one is very close 
to the road.  If it fell over about a 1/4 to 1/3 of it would extend 
beyond the road.  i haven't counted antennas, but there are quite a few 
up there on the different towers. One farm has two that are very close 
to each other and maybe a mile from me.  They resulted in the township 
enacting an ordinance that has pretty much ended more cell towers coming in.

I've been trying to purchase a couple acres behind me, but there is 64 
acres that would be land-locked except for the vacant and heavily wooded 
lot to the North of me so there is no way I'm ever going to be able to 
get that one without purchasing the whole 64 acres.   A lot of the 64 
acres is or would be defined as weld lands  (IE swampy) so only a 
portion of it could be developed.  He told me the taxes are eating it 
up, but he wants to develop it. Also due to subdividing he can not sell 
any more lots...although I've been trying to get about two acres that 
would be added to my property description.

And what's quiet today might not be tomorrow, or next week, or...
