Half Shell is Going Virtual

With the same determination the Federation has to protect our rivers, we feel we must protect the health of our Federation family. With the concerns raised by the coronavirus, we are transforming our in-person Arundel Rivers on the Half Shell into an online fundraiser and auction. The auction date is yet to be determined, but we will keep you posted.
