SEH (Old Glen off questhaven has them in above the backyards and some people in early 2007 were not only asking low 600s for those places, but taking pictures from the street for the MLS with a Tower behind the house). They run down the past Glen Ellen Place. Here is an image from the current listing on Glen Ellen:
I found a listing about a month ago in Carlsbad and one of the MLS images was of the backyard, showing off the view. To the right of the home just over the fence was the top of a power tower. It was probably 10 feet from the fence, a child could toss a tennis ball and hit it.
It amazes me that someone would build so close to these towers. If one could look past the potential dangers (as noted above, it can be argued both safe and dangerous although im in the dangerous court), these things are eyesoars.
