What's wrong with walking a few hills, I'd like to know? Really, you and your bike made it up and over the problem hills under your own steam - you just chose a more, um, convienent method. (At least that's what I told myself on tour)
You could also think of it as cross-training.
Keep it up, m'girl. All forward motion is good. Take pictures, and don't forget to blog.
Give big space to the festive dog that make sport in the roadway. Avoid entanglement with your wheel spoke.
