Jack:

I watched a QDM show a year or so ago.....that said whitetail does appear to become MORE "active" as they're pressured. Meaning....they'll stay on their feet more as they're pressured, more.

What they also said was.....this new, added movement would be due to them taking differing routes (and the extra time associated with doing so)than normal....to AVOID the area they're being pressured in.

I absolutely believe this.
