One of my main Imaginary friends was Penny, the substitute sister for me when my real one was at college. (she was like, 18 when I was 9) Penny had a magical skateboard that could change to any action thing possible...like a snowboard or hangglider or jet pack.
I remember I used to watch the telephone pole lines when we would go driving, cause I pretended she was rollerblading along them--and when they ended, she would jump off and hang glide. Fun fun!
