Is my 6 month old son too young for basketball game?

When is the right age to take your baby to his first basketball game? My husband and I came to an agreement that if we took our son to the game....we would leave the minute he got fussy. The game started at 7pm and left by 9pm(4th qtr). My huz said,  "come one 5 more minutes". I said "a deal is a deal". Payton, my son decided enough is enough!!! LOL we took precautions and took his earphones to keep the noise down. Unfortunately, he did not like the earphones :( Hopefully, he will get use to it soon....a lot more games planned ahead.
