Found a bear

get a Jones Deer Grunt call and set the O-ring to toward the top of the reed to create a bawl: waaaaahaaaaaa (about 1-2 seconds).  You can adjust the o-ring to change the tone and pitch.  Simple to do and the slightest variation can make the difference.

Who carries the call sportsman or cabelas?

both should carry it.  about $12.  If you can't find one, look for a grunt call with an adjustable reed (o-ring) that allows you to essentially shorten the reed, which creates the higher pitch.  I've called in does on the run many times.  if this happens, you know you're making the right sound
