Really look for sign then hunt in the areas that are showing you sign. Not all bears will commit and come to calls.
I have called in a couple of bears, back in 2005 during the spring bear hunt. I believe the dates were May 15 and May 22nd. We did a lot of calling prior to that with no luck. We also had not seen much fresh sign until about a week into May. Both bears were called into a clearcut and both times we started somewhat late in the morning (9:30- 10:00). And, both times the bear showed up at an hour and 15 minutes into the calling session. We used an electronic call with a fawn in distress sound.
