This sounds like a really great event! Check out more information about the Global Day of Coderetreat. I know some of the people organizing it and I expect it to be worth the time for anyone who is interested in good software engineering practices. It is being held in Vaughn, Ontario at the 407ETR offices (6300 Steeles Avenue, Vaughn, Ontario). 407ETR is doing a full Agile Transformation and we have assisted them with a significant amount of training for their ScrumMasters and Product Owners. I’ve visited their offices and they’ve got a great team room set up!
