Scalping is legal in Alabama if you have purchased a $100.00 license to do so. So for the average Joe on the street to be selling tickets, it is not legal to do so.
My opinion on the student situation is this on the student section. Students should be the ones in the student section. The ACT Card should be used for admission. Example, say there are 22,000 students, only 15,000 would have the special bar code to allow entry into the stadium. That would leave 7,000 students on the standby entry. They would be allowed to enter at a certain time point before kickoff up until the student section was full. I'm not sure the exact reason for the student guest, but there shouldn't be guest if there are students that are not allowed in the stadium because they do not have tickets. Hope that makes sense.
