I've been a member for years, I don't actually remember receiving ballots to vote.
However, I don't even know how I'd educate myself to cast an informed vote. Same thing with a timeshare I just got from my grandfather. I received a name, a title, and one or two paragraphs about the candidates. It's pretty daunting to try to extrapolate from that into a guess at who will be the best candidate.
Same thing with REI. I don't know their business, their challenges, and the qualifications or competency of the candidates well enough to have a meaningful say in who should be on the board. Do I?
