I'll be at the RubyConf*MI which is the premiere Ruby event in Michigan.
hCalendar info
RubyConf*MI: Saturday, August 26, 9AM-5PM, at Science Building at Calvin College, Grand Rapids, Michigan
It's just a 1-day conference, but should be a great time. Get to see David Black, author of Ruby for Rails, speak, as well as SouthEast Michigan's own Patrick Hurley.
If you're in the Grand Rapids, Michigan area, stop by.
