I'm starting an 8.5 lb at 5 or 6 to bring to ny fantasy draft tomorrow, leaving at 10 a.m. or a little sooner. How long can I keep it in a cooler b4 it cools & tightens up or spoiling becomes an issue? Around midnight it will have to go to the oven. Rain possible tonight and its the cheap MES.. I'll be able to sleep worry free that way. I want to pull it and put it in the roaster right b4 I leave. Rubbing with Bad Byron's Butt Rub & I'm going to spritz with Dr Pepper & worcestershire.
