Julie, You did not have to go back to the 70's to remember the greatness of BUSH!
Shaving did not really become popular until about 92, 93.
If you take a look back at the Playboy models you will find that most of them in 91 and 92 still had "bush" but it was being highly trimmed at that time. By 93 there was no more bush and it took off with swingers withing a year or so.
Bush has been coming back. Personally I am happy about that but it is what works for others. My choice does not make it right for you.
