Someone else asked this exact question not to long ago and I told them that as long as the finished poster doesn't have a bunch of wires hanging off of it I'm sure it will be ok. Meaning when you make your poster tape all the wires down real good so they are secured to the poster and not flopping around.
Just bring a clear bag,and if they do not allow them you can leave it till finished. Worth a shot
I would play it safe and not use them. Just my thought ...
