Garden Valley Bigfoot?

Right before Thanksgiving, my husband's "anonymous friend" emailed him some pictures.  They have a cabin at Terrace Lakes and he had gone up a small dirt road off the Middle Fork of the Payette to scout for deer.  He took these pictures and explained that the tracks had come off a ridge, onto the road and he had followed them for about a half a mile.

The prints were about 6 inches across - not huge, and the stride was about 4 feet.  Ok, maybe could have been a runner in those weird barefoot shoes, but why would they come off the mountain, go along the road for 1/2 a mile, then off the road and down into the brush?  He's sure he saw the tracks of a bigfoot.

I looked at the BFRO site and found several sightings in the same general area. You know how fascinated I am with Bigfoot.  What do you think?  Jaci, can't wait to hear your thoughts!
