You can
try to fight whatever you want at the gate.
My view:
The people taking your tickets have no authority to change the rules they were given by their management.
Getting a 'Supervisor' on the scene with the authority to change the rules, on the spot, might take a bit of time.
Most err on the side of caution... not what is right or wrong.
Bottom Line : If they don't want to let you and your items in...you will not get in. If you cause too much of a fuss, they will find some petty charge on which to haul you away hold you (disturbing the peace, etc.)
You will then have an option to take your case to court.
Court and lawyer fees are expensive.
There is no law which requires anyone to reimburse you and your expenses, if you are proven 'in the right', in CO, as far as I know.
Best chance, in my opinion, would be to unite with others and other groups willing to share the expenses of such litigation.
I would not want to incur the cost of litigation by myself, just to be 'right'. I can't afford it.
For me, if I really wanted to see the concert, it would not be practical to try and bring any prohibited items with me (like my totems ...see below), unless I was ready to forfeit them or take them back to my car and wait in line again.
If it were me, I'd make a few calls to the City and County of Denver, and to Red Rocks and see what they say.
As I mentioned above, I have the understanding the the laws of the City and Country of Denver prevail at Red Rocks.
I know that there are some Denver laws, with Denver maintaining Home Rule status, such as Open Carry and possession of >20rd mag limit, that preempt State law.
I'd decide which was more important: pushing the issue and possibly missing the concert or seeing the concert.
Please don't misunderstand me. I'm not saying that 'I believe CC should not be allowed in said venue'.
I'm saying, showing up at the gate and pushing the issue there is the wrong time and place to debate it.
Now, if I were a Sovereign Citizen, things would be different ...
Let us know what you find out ...
