Wow, I think I'd be more amazed at seeing the ring-neck than seeing a rattler. I have seen many snakes and I will agree that I probably do over-react, however at our camp on Lake Raystown I have killed (verified) quite a few of copperheads (mostly babies) with the lawn mower. I never even saw them until I had already run them over and killed them. I have yet to see a rattler, my dad and a friend were fishing Stony Creek when I was younger (probably 20 years ago) and his friend shot it. I think that is where my phobia of snakes came from.
As for bears, i have lived near gamelands for the past year and have had bears (mother, 3 cubs) actually on my front porch. I was alarmed to her presence by my dog, I looked out the front window and there she was. I opened the front door leaving the dog inside and growled at her, she jumped off the porch with her cubs and ran across the street. No problem!
About four or five years ago my dad and I were fishing Standing Stone Creek on the first day of trout. A guy came walking down the stream and said there is a bear in that Sycamore tree. Curiosity killed me so I walked up to the tree looked up the branches and didn;t see anything. He said she's in the bottom of the tree. I looked in a hole no larger than a groundhog hole and there she was looking right at me. I backed up and left. My dad and the guy who told us about the bear decided to go up around lunch time and snap some pics. My dad stuck the camera in the hole and snapped a few pics with his disposable camera (they came out great). Dad and this guy walked down stream after taking the pictures and the bear came running out of the tree and ran across a field approx 300 yards. I told my dad I thought there would be cubs in the tree and asked for the camera. I went up and looked in the hole and sure enough there were three cubs, I took several pictures and left them be. Next weekend we went back and they were all gone.
Two years ago we were hunting bear with a group of guys and the first bear to come out attacked the one guy who was in our party after being shot several times. The bear after being shot at least three times had enough strength to grab a hold of the guy and bite and scratch him before it died.
The moral of the story is if you don't mess with them, they won't mess with you. Bears are not something to be afraid of, now snakes thats a different story! I'm just kidding, this post has really opened my eyes concerning snakes.
Here is a picture of me with one of three bear cubs that was brought in to a wildlife rehab near my house, looks like a black lab pup!
