My question involves criminal law for the state of: Alaska

1. If I am over 21, is it legal to be at a house party with people who are not 21 years of age?

2. Does it make a difference I am consuming or sober?

3. This question assumes the fact that I am NOT supplying any alcohol to ANYONE.

PS: If you can find an actual law that pertains to this, please post the link, but any and all answers are appreciated. Thanks!!
