If worst come to worst just bring it back to a boil later on and then chill it. Not time efficient but will sanitize the wort if you have to leave it for a while.
Exactly what I thought! SWMBO made me go to her parents house with her. I was gonna stay til it was done and drive over there myself. Ended up cutting it off about two minutes early. I just tossed in the aroma hops and threw the cover on the pot. They got a good forty five minute steep. Should turn out fine!
