Seventeen years old is the age you can enter into a contract in Tennessee. The legal age however is still eighteen.
The legal age to enter a bar in Nebraska is 21. You can enter a bar at any age as long as you are in the company of your parents or your legal guardian.
It depends on the club. Most clubs are 21, as the legal drinking age is 21. However, some clubs host college nights and the like, where 18 year olds can enter, and those over 21 are given special stamps or bracelets to signify their age to the bartender. In theory, a club could open it's door to all ages, but state laws and/or insurance liability would probably prohibit alcohol being served, so it is unlikely that a business would open an all ages club.
