The Humanists of Greater Portland is offering a free 6-week class/discussion group on the topic of logical fallacies, starting Jan. 13th, 2013. This Westside discussion group is not a co-sponsor, but it is listed here as it may be of interest to people of all belief systems (theist, atheist, etc.). The atmosphere is intended to be neutral, so all will feel welcomed. Attend as many, or few, of the sessions that you desire.
For all details for session 2 of 6, and to rsvp, go to their meetup
website here (rsvp's not enabled at our meetup group page):

It is located near downtown Portland. Since this is on a Sunday, traffic will be light, so feel free to come from the outer reaches of Portland.
