Its a very good strategy! When I hit an unfamiliar town...I zoom around with the satellite view.....I find an old school, cemetery, RR tracks, millpond etc...and then find the nearest swimming water...
downstream from the RR bridge over any little old creek has been an informal swimming hole for years...the creek never leaves the bed there downstream...
Any thing you can use to narrow down this huge Planet for hunting spots is helpful! Especially in America, where its only been inhabited by metal droppers for a relatively short time...coupla hunnerd years and in some towns a lot less than that...
But yeah, you gotta find the old swimming holes if you can! Folks didnt have AC! Not even in the 60's! So yeah...Super huge good thing to ask around and hear the stories!
