I had been wondering on how to fully examine yourself for ticks after a solo hike and I had stumbled onto a way to examine areas you cant see. If you use a mobile phone with a camera feature on it, you can take a picture of the unseen area and check the picture with varying angles and can zoom in on suspect areas. Now I am not saying that this is 100% full proof, but it does give you more tools to detect ticks before they imbed for a longer period.
