We've gone a couple of times, most recently two years ago. Did the "group" ride once, but ended up riding alone the whole time as it's mostly a leave-when-you-want ride with cue sheets (although, it is a nice route). It's kind of a low key affair, held in a local elementary school. The gym is filled with lots of beautiful bikes to drool over, and some accessories for sale. If you are looking for a new tandem, it's definitely worth going, as they have a great selection. If you see a talk that is of interest, then it's probably worth it, too. For us, since we didn't really know anybody and already have enough bikes, we kind of just looked at the bikes, listened to one talk, and then headed home. We had hoped to connect with other tandemists in the area, but apart from some polite conversation, that didn't really pan out.
