There are plenty of ways to convert US dollars into Bitcoin, without exchanges.

For one, an often overlooked and dead simple way: you can sell goods/services and tell your customers you accept Bitcoin.

You can buy bitcoins for cash from sellers you meet face to face: https://en.bitcoin.it/wiki/Category:Directories
