Bigtex.com doesn't say how to enter the fair with a concealed weapon, only that it is allowed. They do say open carry is prohibited. I found the rules, taking from people that recently have done it. You declare concealed carry to a gate attendant or police officer. They will record license info., send you on your way. You must have you CHL license with you and probably your drivers license. They used to make you go in on the side by the trains.
