If you get the chance you might want to attend the Mapper-Modeler conference held by Google in Zurich, Switzerland. Read more about it at the SketchUp blog HERE.
Briefly, to apply for a spot you must fill out a form and provide the following:
- Collection of models: A link to a 3D Warehouse collection that contains geo-models you've built and contributed
- Brief statement: A short paragraph (3 or 4 sentences) that outlines what you hope to gain by attending the conference. Please also mention any special knowledge or skills you might be able to contribute.
EDIT: Someone pointed me to www.kayak.com as a way to begin planning a trip easily.
