Poison Ivy

So I don't really know what it is for sure--some say it's poison ivy; others say they're spider bites. But since our first week here, I've frequently had new itchy rashes show up on my arms and legs. These are just a few of them. (Sam's also had his share, but in different forms.) We've been outside and in the woods a lot, and poison ivy seems to be everywhere. I thought I was being careful, but now I'm really careful. And paranoid of any unfamiliar plant.
