To answer the question here: Sandra said no, they will not be having tours 2017. However, they plan to in 2018. "I will post a 2018 schedule as soon as I know more," she said. Apparently they're doing some construction right now, but I don't know the specifics.
I wish the site was more informative and updated in a timely manner. The "Events" link isn't clearly labeled as such, and even then it's just a calendar plug-in with no actual information. I pointed out to Sandra that the site doesn't give any indication what the plan is this year either way. That was over a week ago. Nothing has changed. It wouldn't take much to post a note saying, "No tours in 2017, but stay tuned for news about 2018!"
I'm not sure why the main site and this board are so severely neglected. There are several threads on here with unanswered questions going back years. (Some have been answered. Others inexplicably ignored.) The most recent post on their Facebook page was in August with some replies a month ago, though no official and concise statement regarding the status of tours for this year. I mean, the info is there, but it's buried in the comments on an unrelated post.
I had some luck emailing directly, but if I ran a huge semi-annual event and had 1) a website to advertise it, 2) set up a board for discussion, and 3) a Facebook page for it, I'd use the web to disseminate information efficiently, accurately, and in a timely manner to everyone interested.
