Our RenFest is also super spotty with cell coverage, so that’s nice. GMRS uses the same bands as FRS, so they’re compatible, but GMRS allows 1) Removable antennas for better coverage 2) More power (FRS 2 vs 50 watts on GMRS) 3) Repeaters for very wide coverage (I hear people talking from 60+ miles away on a local repeater once in a while).
The radios are more expensive, starting around $20 but the benefits are pretty nice.
Lol me either.
