Hi Andy, 
I do make a natural poison ivy/oak/sumac product that I would say 99% of my clients love.  I myself have had to use it many times because I love to garden and pick many of my own wild herbs.  I've found that the itches are not always caused by plants and regardless of what caused the itch I always use this stuff and have had alot of success.  If your interested you can go to my site www.rabbottsremedies.com and look for it / otherwise I would recommend familiarizing yourself with jewelweed.  In CT it's about 2 to 3 inches high.   
Good luck and enjoy your camping.  Ruth  |
