Quoted:
Are you really going to have it on there during the drive, or just toss it on the engine block after you get there while doing the final packing up for the hike?
And, for fuck's sake, can we get some other ARFcommers in here to help out Sev89 ? He's trying to get chicken advice from a fucking vegetarian, and this is all I've got.
hahahaha I had no idea you were a vedgetarian man. Now everything you've said makes sense. (not laughing at you, laughing at myself for being so damn confused)
Yes, you leave it on the block while you drive. Literally you place it on the engine block / intake manifold / exhaust manifold / etc (obviously where its not going to get sucked into the belts or whatever) and drive for X time
the driving keeps the engine at a consistent temperature (if you're on the highway and doing a constantish engine speed)
So when you get to the trailhead, you literally pop the hood, pull out the foil packs of food, throw them in a ziplock back and put the bag into your backpack and hike.
Edit: Just so everyone knows what I'm talking about
