Last week, I packed my bags and headed for Norfolk, VA to speak at the Mid-Atlantic Developers Expo. I've spent the better part of the past year traveling the country, speaking about Geospatial Programming using Ruby and Rails. As a long-time lover of maps, the topic has been a joy to introduce to the community of Ruby developers, at both small regional conferences like MagicRuby or MountainRuby, and at major national conferences like RubyConf 2010 and RailsConf 2011.
