I'd certainly make the trek down from Ontario. Taking nothing away from the two-day programs now offered, I know the value and benefits of taking things to the next step in building a strong foundation to work from. Coming from 30+ years as a tech teacher, corp. training director and training consultant I appreciate the need for both types of programs. IMHO what David has outlined could easily be spread over 5 or 6 days without being forced to branch off into individual interests to any significant degree. One only needs to look at David's web-site to be inspired.
