I've hunted at towns and hamlets along the Rte. 66, as it goes through the desert in So. CA, and some spots in Arizona. Just the predictable coins of the era for that road, at old auto-camp pull-off spots, parks in cities along the route, etc..... Wheaties, silver coins (of the auto-era), etc... Naturally some of the cities along the route are older than the origination of the east west road of the name-sake. For example, they could be originated from earlier mining towns, or RR Towns, etc.... And as the auto-roads began to lace from east to west, naturally they would follow/connect towns already in existence, and also simply follow roads (trails, routes, etc...) that were already there. Because of course earlier travel routes would already have gone the "path of least resistance" from a topographical perspective. So we of course found coins that predated the "rte. 66" namesake auto-road. For example, in Needles, CA I got some barbers, IH's, and a $1 gold coin, that would have predated any people-traffic from the days when that was a Rte. 66 hub.
