Navigate terrain using radio signals instead of maps. ARDF (Amateur Radio Direction Finding) is a legitimate sport: find hidden transmitters across open fields using a portable receiver and directional antenna. It combines orienteering, radio knowledge, antenna design, and navigation skills. The competition aspect keeps it engaging; the technical challenge keeps it interesting.
