Now, before I even go ANYWHERE with this, This is not a question on whether it should, or should not be allowed, or anything like that. This is not a debate against the pros and cons, or fors or againsts. Personally, I Prefer concealed carry, but I am interested in the laws on firearm carry as a whole, and this goes towards understanding that.
I am simply wondering what laws specifically Prohibit Open Carry.
So far, All I know of is TPC 46.02:

(forgive the image.. the new phamphlet does not allow copy & paste! Aargh!)
Are there any other restrictions elsewhere that prevent it?
I Am going somewhere with this, just want to be sure that this is the entire basis against OC in Texas.
