I'm really enjoying riding my bike on the trainer but I think I may have to stay in the doorway for quite a while yet. I tried riding in the middle of the room and completely fell off my bike about three times. I decided not to push my luck and moved back to the doorway. I could just imagine the emergency room conversation if I'd really hurt myself:
ER Nurse: Ma'am, how did you get injured?
Me: I crashed my bike.
Me: Um, in the house.
Nurse: What were you doing?
Me: Trying to watch TV.
