Why didn't you just tell him to park near the first recognizable building he happened to drive past (post office, supermarket, whatever...) and wait for you to meet him there ? I'm pretty sure this would've taken a lot less time and caused the poor old man a lot less stress.

Wouldn't it be easier for him to stop, you pinpoint his location, then you go get him so none of that would have happened?

Silver alert!

I really hope you found him before posting this. I mean seriously. You did prioritize finding your grandpa over making an FML...right?

Did you find him?

more of an FML for your gramps. I'm sure he would post, but his phone just died. does find my iPhone work off the last pinged location? crap. location was turned off? time for the picture on milk carton approach.

Please do a followup on how you eventually found him. :D

How about ask him what street he was on? Or where he was near?

Several hours? You're not a very good teacher, I guess.

As opposed to just asking him to find the nearest street sign or business? He didn't need to master the technology. You just needed a little common sense.
