basically, i know exactly what i want to do, but when it comes to various ideas, what are some general rules i should follow when it comes to haunting my garage. my haunt consists of 2 rooms (11X11) and 2 hallways, one about 3 feet wide, the other closer to 4. does it need sprinklers? is it too big with too few exits (one garage door)? should i have insurances? i need some tips!! thanks!
