Honestly, I was in favor of it but then I put aside the hype and I think its best if it is kept at 21. There are lots more kids who don't get booze but want it - maybe the kids who dont go to parties or whatever. And imagine all the drunk kids on the roads! THey think they are invincible and will be drunk doing dangerous things, more importantly, endangering other people.
I am 18 and I feel it should be kept at 21.
