Here are a few groups of sketchers that you might be interested in meeting. The Meetup group regularly has interesting sessions and meets. The Skytrain Sketc Group meets every Sunday at 4pm at the Waterfront station.http://www.meetup.com/The-Vancouver-Contemporary-Artists/members/http://vancouverskytrainsketchgroup.blogspot.ca/
Let me know if these interest you.
You can also go through the Vancouver postings for the last few sketchcrawls and check some of the people there.
I will start getting out and about now that the weather is getting good and the days longer.
