Depends on the show, probably not. Flash is never allowed. Check your ticket & their website. Cell phone cameras usu OK.
Yes you can if you don't disturb the crowd with it
I suppose so. I guess it depends on what's going on, but normally I don't thing why not. Remember also that this is in Denver and parking is to say the least dificult. I guess that if there is a production, they make sure to put out (publish) that type of information or at least the number for questions, etc.
When we went for our event they allowed them, they just had to go through the bags, etc.
