ShannonAR15:
Federal Law and Mississippi Law are Two Different Things, Entirely.
Under Federal Law 18 U.S.C. 922(q)(2), you would be Fine, however; The Same CANNOT be said under Mississippi Law, more Specifically, Mississippi Law 97-37-17.
If I were You, then, Knowing that This Event is School-related, even at a Bowling Alley, I would Follow Mississippi Law 97-37-17(6)(a) through Mississippi Law 97-37-17(6)(c).
Leave The Firearm in The Car, unless; You want to 'Play-with-Fire' on a Mississippi Firearms-related Felony Charge.
*** Next Year, go to Jackson, and Loudly Complain that Mississippi State should Add The Following: (9) Nothing under This Code Section shall Apply to or Effect any Adult, not being a Student of such School, from The Possession of any Weapon on Educational Property if such Adult is in Possession of a Valid and Lawfully Issued License to Carry a Stun Gun, Pistol, or Revolver if such License is Obtained under The Provisions of Mississippi Code Section 45-9-101. ***
