The Michigan Ruby Users Group is hosting RubyConf\*MI on August 26, 2006, in Grand Rapids, Michigan. It is shaping up to be quite a conference! It will be a full day, single-track conference featuring well-known speakers David A. Black and Pat Eyler.
If you're in the region, spread the word! Registration will be $20, which is incredibly inexpensive for any conference. It will be well worth it! (the free lunch alone is almost worth $20.)
