...My general mantra is training, training, training! I can't see anyone who ventures out of an urban area not benefitting from a basic 16 hour WFA course! Well worth the time!

WFA is great, but if you've got a week, I think WFR is the best value in medical training. An 80hr course sucks up a lot of vacation time, but the ratio of time/money spent to knowledge attained is crazy.
