Now, pennies are zinc. I'm not sure how zinc
rates, on hardness. Harder than copper, I'd
guess.


Every now and then would find those explosive devices used to strap to the
track that when run over would make a super loud bang to alert the
engineer to stop the train. Ever find those?

Although handy to walk along the tracks, I quickly learned to walk along
the OUTSIDE of the tracks! as in yeccchhh!!!
