> one has ever come around during one of the few black outs we have had.

> site.

> Also from what I hear, HWA also has a UPS on site that is just lacking

> the tel. co keeps up theirs)  I also have a generator that can power my
> house, so all my electric uses could continue as long as I have fuel.  I
> have several cars with fresh fuel, so I could keep going for a long time.
> Bottom line:  We could put together an automatic system for less than 1k
