If you have the only tower and only place to put a tower in an area,,your probable good, but the technology is changing quickly, and the cell phones will end up all being Voice Over Internet Protocol in the not to distant future, which will mean they only need antennas for delivering internet service to your phone/device,,will that drive down the value of cell towers, who knows, but the person selling that tower may know

It is the nature of the beast.One down side that I have found with mifi service is that you are stuck carrying two devices (ipad and mifi) if you want to have internet service.

All such devices now fall under the extensive rules and penalty provisions of Property Code sections 5.061 et seq.

I hope I'm not seeing this as you swapped out each device with an ungrounded outlet with a 3 prong (perceived by tenants or anyone else as grounded) device.

And many people think these devices are snake oil and that the only fix is a new leach field, which costs several thousand dollars.  

So then, after 7 1/2 hrs of arabic.. we would really begin to study. 345pm till 7pm monday through friday. 70-80 new words in that timeframe, memorized to the point of instant recall using pneumonic devices and scenarios (thats where group creativity was crucial).

@Alvin Grier Time to re-think your strategy.Essentially, you have depended on a single lead generation device that is illegal in most locales.
