"Assuming I'm indoors/ bugging in, I'd be making camp upstairs. I don't think it would set off any alarms to leave a bunch of broken glass or other small, noisy items laying around the floor. Assuming anyone came inside, the crunching of whatever is beneath their shoe would alert my dogs (assuming I didn't hear it)."

"lol, I'll eat the tutu before I eat my babies."

"Good idea. Actually another benefit to this is that, in an Apoc situation, broken glass and the like wouldn't necessarily be all that out of place, so if a Raider rather than a zombie were to step on it and make a noise it wouldn't always stand out automatically as something that somebody deliberately set up to make a noise. That way the noise would alert you, or your dog as the case may be) without by default alerting the trespasser as well. Other zombies or other Raiders wouldn't automatically come a'running just because one of their own stepped on a bit of broken glass, because there'd probably be broken glass everywhere."

"Yup- pretty much hit the nail on the head. Much less obvious than a siren blaring out "Danger Will Robinson Danger!!!" (lost in space anyone???)"
