Electric Avenue: both music and power you need

It reminds me my first electric car rental experience.  I rented a Nissan Leaf couple months ago and thought it should just like a Prius of Toyota, which I've car-shared so many times before (thanks to Phillycarshare and Zipcar).  The interior of the Leaf looks pretty similar to Prius, the power bottom, the navigator, and instrument panel.  While I was driving it and watching the power bar (I thought it was Gas bar) going lower and lower, I think i might need to fuel it up at the gas station!  Just about to fuel it at the Shell, I found that Leaf is a total electric car!!!!  
And I realize that trying to find a electric power station in a city is difficult...

Here in downtown Portland, Oregon, a street called "Electric Avenue" which it offers about 5 electric power-fueling station sponsored by different companies.  All you need to pay is the parking fee for the time you fuel your power.  I was quite excited to see this "Electric Avenue" since I know how hard it is to find a electric station.  

Portland is a city full of green technology.  The green street projects, green buildings, and the electric avenue, who said that artists don't care about green?
