10-4 good buddy.
sorry had to say it . it made me laugh.
i would say in an emergency / natural or man made disaster old tech can come in very handy. cell batteries usually dont last very long when using apps that use radio/ antenna(especially when constantly searching for signals) &/or lit up screen. and if theirs no electric the cars is the only source to charge them that may cost presious gas you may need. double A batteries are cheap to stock up on. cell phone broadbands and signals get clogged up in high usuage you get texts thru easier though. cb or other personal short range radios and scanners would help locating people(friends family authorities) & other things you might need to know about or find or avoid.
