I have been reading about all of the charging stations in Chattanooga, TN and have the opportunity to take a quick trip up there this weekend for a day/night. Has anyone used any of the chargers in downtown or at the local sites (Ruby Falls, Rock City, etc.). I see that the chargers are free but belong to the Blink network. Will I still have to have a Blink card to use them even though they are free to use (I ordered one today so obviously I won't have it in time)? I was planning my trip based off of these chargers: lunch at Cracker Barrel that has a charger on the outside of town, visit Ruby Falls for a couple of hours, and then have dinner at a downtown resturant with a charger. With all of these stops/charges, I should be able to head back home with a full charge on Sunday (assuming I can use the chargers without a Blink card). If I am not able to use them, that will change my plans/trip a little (lunch/dinner somewhere else, use of Mountain Mode to save some miles for moving around the city, etc).
