Funny... I was just reading an article about this the other day. Hi pressure or low pressure don't matter. What gets deer active is when the pressure is moving. When a cold front comes in, the barometer drops, when the pressure is moving the deer want to feed. Activity slows once the front has settled in because the barometer has stopped moving. As the front passes the pressure starts moving up again and that triggers more movement until the pressure becomes steady again. Supposedly, the "ideal range" for the barometer is 28.8 to 30.3.
With that being said... if you have the chance to hunt, go for it, but according to what I read you might see more movement if you are sitting as the leading edge of a front comes through.
