Yes El Cabong, I also use cooking fires, chem stations and forges for only as long as I need them while in SP, then shut them down. However, I have recently been playing with a group who thwarts this concept. They load up everything with fuel, turn the damn things on and leave them burning, even during horde nights. 4 forges, 2 cooking fires and 2 chem stations. Mind you, the base has steel grate fence all around, and auto turrets. Many screamers throught the game day, and if the turrets don't get them and the screamer is bashing on the front steel door, someone just goes and takes her out. These guys don't live in fear. Suppose there's a stage in gameplay where its a case of 'Come and get me'. For me in SP. I err on the side of caution just like you.
