I live near Richmond, and there are certainly plenty of appropriate spots nearby. I'm just sort of weighing the idea of how much fun a field trip could be against the effort that might be involved in tracking down a snake that is, at the end of the day, pretty common in this area (we have one in the family room, after all). I grew up in the mid-west, and our yard had lots of garter snakes in it, and I handled them often and released them shortly afterward. And since moving to Virginia I've seen snakes in the wild--copperheads and water snakes while fly fishing, rat snakes and milk snakes in yards--but no corn snakes (though I haven't exactly sought them out either).
I guess since I've never deliberately gone on a field hunt for snakes, I'm thinking about the process. Bird watchers tend to congregate in particular areas that are known to contain particular species, and fossil hunters and rock hounds are familiar with productive sites for their pursuits. I was just wondering if there were famous corn snake "hot spots" in Virginia. The process is probably more like fishing, in which one reads the water and develops techniques for effectively finding trout even in unknown rivers. And yet there's always something comforting about fishing familiar water where one can focus on spots that have been particularly productive in the past.
