Interesting stuff indeed.
If you have decent mobile phone and net connection there is the lighting map but this would be handy as small compact and lets you know. Last thing you want is to be up there in middle of a storm.
My first experience of lightening strike was out on me M/C following another gent about 20m apart and it was chucking it down. God almighty flash and hello where’s me mate gone. Found him in the hedge smoking and pulled him out. You could see the burn marks across his back of his denmin jacket on top of his leather jacket and hole in the seat of his M/C the battery well was toasted and the electrics pretty much fried. Pretty much shock up big time but well alive.
HOW MUCH ouch 
, hmm small Trans AM radio yes good alternative.
Now surely the biggest danger is build up of static voltage on antenna system. Used to have a very long wire at 25ft high and was 100ft long for SWL my meter i had did 500v even seen that go off the scale before even a storm arrives in place used to live very high on hill to local surroundings. Even set up a spark gap to earth and seen it jump 2cm gap. Scary stuff . Set up a resister between earth and me antenna to stop the build up of static.
