I think my first Linux distro was actually Yggdrasil, but right after that I tried Slackware and found it was much more complete and easy to use. You could also order a 4 CD box from Walnut Creek with tons of packages.

I kept subscriptions from Walnut Creek to both FreeBSD and Slackware for about 10 years. They would automatically send me new versions as soon as they were released.
