Due to scheduling conflicts, there will only be one Auburn session in August on 8/23. We will resume having 2 sessions in September, on 9/6 and 9/20. The forum thread for those jams is here No new special sessions have been announced for Burlington, but the weekly classes should still be going. Info for that is in this thread, and you can contact Rafe with more questions.
As always, there is more info and discussion about gym sessions in Jam Planning and you can check the calendar for updates.
