Good luck!
I "learned" for the first time myself, this summer. A friend spent about an hour in early June showing me the very basics; I then spent three weeks in a crowded, pedestrian European city, where I decided to throw caution to the wind and rent a car (manual, because that's all the place had). It was.... interesting. : ) Once they figured out I basically couldn't get their car to move three feet, they very nicely showed me some basics and let me practice in their garage for an hour and a half. Right about the point I realized it was stupid and I would have to be certifiably insane to try to drive on dense, urban streets with my negligible skills, a moment of insanity triumphed, and I drove up the ramp, out of the garage, and away. Going back would have been roughly impossible by then, so I was off!
It was pretty fun. I won't pretend it didn't have its stressful moments, but it was super enjoyable, and I got much better as the day went on (and I got out of town). I'd do it again in a minute.
Good luck!
