Whew...I was reading thru this thread thinking I was the only one!
We have a coded lock on the laundry room door, which we don't use. And if I had to find the right keys for the right doors I'd be about a hour, first to find the container of keys, next to try them in the various locks. Every once in a while I think to myself I need to do that....so no, no deadbolts here. A large dog, a gun but not deadbolts. And yes, neither the dog nor the gun guarantees our safety in the event of determined break-in, although perhaps it would help if it was a random drunk person (not to many of those out on the farm that don't already live in the house, but hey you never know....) If someone wanted in bad enough I doubt the deadbolt would stop them. All but two of our doors are glass french doors, and those other two have glass as well.
