Why yes, yes I do.
You will be fine. Tell them your going to a timber framing seminar. In the unlikely event that they give you grief bring along some documentation that references the workshop to show them.
Pro tip here, don't use the word "school". I did on one trip to Heartwood and was hauled in the building and held up for several minutes while they tried to figure out how I can be going to a school and not have any student docs.
