The Explorer's Society sounds like a good resource, but it's of no use to me. If the image had already been available elsewhere, I don't know why they used the term "...an exclusive members-only preview..."

I couldn't find anything else though. If they want to keep the product hidden away for members only, that's fine, I'll just spend money elsewhere.
I would say that they need to work on their marketing strategy a LOT, but the marketing manager for Pinnacle is Joseph Unger, and I've always respected every other Unger I've known
