The Society Seneschal, A.J. Pongratz, has provided legal guidance for Youth Combat activities at Pennsic in light of recent changes in Pennsylvania law. The full text is quite long, and is posted in full at The East Kingdom Gazette  http://eastkingdomgazette.org/2015/07/01/societys-guidelines-for-youth-combat-at-pennsic-and-changes-to-pa-laws/

However, the pertinent part of the statement is:

In reviewing the official website of the Pennsylvania Department of Health and Human Services and the recent statute with other officers and agents of the SCA, I have determined that this statute will not impact on Heavy Combat or Rapier Combat by minor children of the age of 16 or 17 nor youth activities.
