The Bass Pro in Tempe, AZ has the tracks in the floor. I am guessing this is standard. There is a flyer that describes the prints but I can't recall that they are easy to find in the store.

They use Cougar, duck, beaver, bears, coyote/wolf, deer, the usual prints you may find in the back country. My son (age 5) and I like to follow them and discuss what they are doing.

Funny you mention Bass Pro. We are taking my son there this weekend for his annual Christmas photo with Santa Claus.
