Well, that was dumb. I really should have researched futher on my own. Here is the answer:
"f. Weapons. No person may enter a Transit Facility or board a Transit Vehicle with a concealed dangerous weapon or firearm, except persons holding a valid permit to carry a concealed weapon, and except as otherwise permitted by law."
Well, I am glad you found the answer.
This should be good considering it was only a short while ago that someone was assaulted at the U of U Trax line at the Stadium.
So carry with pride & the knowledge that should this happen you will be prepared. Remember to always be vigilant of your surroundings. Most assaults occur when people are not paying attention to what is going on around them.
