21cExp did the CD thing one better and sent me a portable hard drive full of music. One of these days I will return the favor and reload it and send it back to him.Since you're not, try doing what Moot & I did years ago: burn CDs to trade [mail is cheap] and get exposed to some things you maybe never heard before.
Cheri and I have also traded books via the USPS. Yeah, what she said, a great way to get exposed to something different. And what xiggi said: "It's all about variety."
