Copperhead, I'd walk out. It would be near impossible for a copperhead to kill a healthy adult. Maybe a small child or someone with serious health issues. I've known a couple of guys who never went to the hospital after copperhead bites. They had some swelling and pain for a day and were fine.
Rattler's are a tough call for me and something I've given some thought to. I'd probably just die. Many of the places where I hunt/hike have no cell service and even with a partner it could be an hour hike back to the truck and another hour drive to cell service. Then figure at least another hour for help, even a helicopter. I know when I go into these places that I'm probably at least 5-6 hours from getting to a hospital if I have to depend on someone coming for me. And maybe a day and a half depending on the situation.
