wash your hands. often.
You are from a city, so prob have some street smarts.
Big danger you will have is American beer.
American beer is like DAB from Dortmund. International hikers get more trail magic as they are more rare, we hiked with a Brit and he got twice as much as us. (not that we were looking for it, just thankful and noticed the difference).
Agree with turtlefast. Watch your footing. Falling is the biggest danger. Like anywhere else you may run into a few drunks and the like but thats just a matter of hiking on. Common sence works. Have a fun hike. Campbell Country is a thing of the past and even that wasn't bad.
American beer is like making love in a canoe............
I sure am looking forward to some though.
Hope the earlier post about foreigners getting more trail magic comes through.
I'll be carrying a boxing kangaroo flag, suggest OP carries a German one.
