LOL Yea

Would probably get ya Snickerd at but not much More
Unfortunately at my age (59) , there ain't many older Timers around any more
But Seriously,
I am not the type of person who can just walk up to strangers and start rambling.
I've always respected peoples space & privacy, As I normally Expect of others.
however What I normally do when out treasure Hunting,
is if I see someone nearby, I look them Directly in the Eyes, Smile & Nod, Then go back to my business & Hope they are the type of person who talks to anyone who will listen.
Once the Conversation gets started, It can usually be manipulated to leads.
an Past friend of Mine, Very Colorful & Recently Deceased was so outspoken,
whether he was on a bus to Atlantic City, Or in a Bar, He would carry a cigar box of Fake finds.
If he knew I & most others knew they were fake finds I don't know. But it wasn't hard to tell.
But anywho..... He would Talk about his Fake adventures Loudly to the point people would give him leads.
Bad thing B.S.'rs most likely attract more B.S.
Just smile when your doing your thing.
let people know your approachable & manipulate those conversations would be my suggestions
