I think over 18 would suffice, don't you? It really sucks being in the 18-20 age range. For a good two years of your life you're not quite considered an adult, yet you are no longer a child. What are you really? Just in the state of being until the time passes by... no one really cares about you... you're just there and can legally purchase cigarettes and porn. Woo?
Sorry. Don't mind my lament. It'll pass... once I hit 21.
I suppose if you MUST make it over 21, when we "kiddies" are ordered to leave, we can all meet up at my apartment and put that privilege to rent porn to good use!

Corrupting the under 18 crowd sounds like some fun, laughs, good times!
