Narrative:

I taxied out from FBO on ground control. Ground told me to stop and call tower when ready. Tower cleared me for takeoff and right at rotate tower said that was a taxiway. It was raining and I did not see the taxiway signs and this taxiway was not close to runway 31. I thought that when they told me to stop and call tower that was the runway I was suppose to takeoff on.
