On or off trail?

[hydethebeef]

Do you prefer to hike on a trail or off the trail? I like to look for natural deer trails to follow because I love to try to understand the travel patterns of wildlife.

If I'm not mistaken, there are several topics about off trailing. I guess we can convert this thread into following animal trails.

I can distinguish a trail but I don't know how to determine what kind of animal made that kind of trail.
