BootCamp USB MBA 2010?

How can I create a bootable USB for Windows 7 on my Macbook Air 2010?

So far, it looks like I need to create the bootable usb drive on a PC.. and cannot on my MBA...

Did you create the USB thumb drive within the bootcamp assistant?

Doesn't give me that option on my MacBook Air 2010... says I need an optical drive.
