In looking at the map of the DFW area, the stations are usually at new car dealers (which have some sort of electric/hybrid cars they sell new (Nissan, Chevy, Mitsu, etc.), Walgreens and CVS drug stores, some shopping centers, some restaurants, and such. Not very many Teslas, although there is a Cadillac store that also sold Fiskers. Closest Tesla sales place is in Dallas.
For many people, the hybrids make sense. Especially people who don't venture out of a 10 mile radius from their home, very much. Battery technology will be the key.
For smaller towns which desire to have tourism, charging stations can be key, in the future, I suspect. Not sure what it costs to put in a station, but it might depend upon if it's a normal charge or "fast charge".
Enjoy!
