I wonder why colorado has so many red areas around hiking trails. Is it just one guy with a bad device who loves to hike or is it because there's bits of radioactive ore on the trails or something?

> From my observations it also seems to vary a lot depending on how the person recording behaves. Some people just walk around logging reading along the way.

I think if this is only what they allowed it would be a useful since it would measure real world exposure.
