Ken, I did remove it and it looks like the mouth piece(s) are still attached. It couldn't have been in my leg for more than 4 hours, so I'm not too worried. It's been a long time since I had a tick; I'm surprised the bite area was actually a little painful (no worse than a thorn or scratch on the skin) and looks a little bruised (very localized and small, right where the bite was). I've taken a few photos on my phone (right after removal and last night) and my new friend is currently in a ziplock in the freezer. I don't expect any of this to amount to anything, but these are easy steps to take should I notice anything down the road.
Even though I was wearing running shorts, I didn't notice the tick until I was sitting in the car. It was on my upper thigh. I was already on I-84 heading west so I waited until I got into Portland to pull over somewhere and remove it. I had my FAK with me, including a Tick Key and a small pair of tweezers.
I actually had some problems using the Tick Key. This could be because of user-error, not realizing the correct direction to "center" the tick into the slot. In theory, it shouldn't matter; the tick would forced into the narrowest point and pulled directly out away from the skin. However, for me, the tick was either small enough (or I was making some mistake) and it kept slipping out of the slot. I ended up using the tweezers, grasping it low and slowly applying force until it released.
Todd: I was very surprised that it attached to my upper thigh, instead of going just a bit farther north . . . .
