I'm not sure if its been asked before and I couldn't find anything on this. Does anyone know if Copperheads run in packs or anything similar? More particulary, my question is "if you see one, does that necessarily mean there are more copperheads near by"? I found a VERY large one last fall trying to enter my garden. It got killed (don't be hatn' on me). Does this mean there are more? Maybe babies or a mate or something to look out for this year near same location? Having seen that ONE, should I be extra vigelent this year when gardening?
