Archery Headquarters recently had a Groupon for a one-hour introductory lesson. The time is kind of inconvenient (6-7PM for the Groupon folks at least), but it was a cool experience. I have zero archery experience, and the instructor (Barry) gave everyone a clear but concise lesson on how to hold a bow, nock the arrow, and release the arrows. Barry seemed to truly enjoy teaching and practicing archery, and his enthusiasm helped to make for a fun experience. We had a great time and would definitely recommend.
Archery HQ has several more courses for people who are interested in improving their skills. I haven't participated in these, but at least from the intro class, I would anticipate the rest of the courses to be worthwhile.
