Well, it's gone from a raised red itchy (like a mosquito bite but two inches long) to red around the edges, and somewhat yellowish red in the middle with those raised bumps that are classic poison ivy (been checking how the plant and the rash look like online.) It feels kinda hard and dry in the middle even though it is covered in hydrocortisone cream. I swear I did see some low-to-the-ground ivy that matches what I saw online, on some parts of Phil's trail. Could be an impostor but who knows, and I did wander off the trail several times too, to take some pictures. Oh well, I'll be out there tomorrow again and will be more careful (and use Deet as I got bit-up by mosquitos too.)

Strange that I've been all over the west camping and never had a reaction like this before. My home trails have poison ivy all over and I have stepped in it and touched it with no reaction (I did not know what it was at the time but found out later.) Maybe I was just plain lucky before.
