I woke just after the event happened. I normally scan Napa city and county (along with tons of other stuff). I thought it was crazy to 'all of a sudden' hear so much traffic at 3:30 Sunday morning, especially after the normal stuff had died down. The two most notable channels that really came alive for me (albeit not at 3:30) was CHP Grape and Cal Fire CMD 1.
Wife got a breaking news notification via e-mail Sunday morning...aprox 8 a.m CST Monitored the Napa County Fire and CAL FIRE LNU East fire OPS audio feed....it was the only one that I could find not knowing any better.....quite impressed with the ICS ....first earth quake OPS that we have ever monitored.
