I'm not giving a huge amount of notice on this, but it works out that we are free this upcoming weekend so we are going to do this regardless of the number of confirmations (I'm posting it more as a open invite for people to tag along for an activity).
The majority of the education center is indoors and there seems to be a lot of covered walkways so we'll be doing it rain or shine. Here's a video about the rain drums (http://www.youtube.com/watch?v=Y9hRggEmZB4)
We'll finish by stopping in at Twede's Cafe for a bite to eat and chit chat http://www.twedescafe.com/ - with a nod to Twin Peaks, of course.
PS I'm going to bring an umbrella anyways 'just in case'
