One thing you can try to speed up the action, is put more excitement in your calling, if you're using electronics to call, kinda hard to do, but if you're using hand calls, blow harder, quicker, and longer, and try to shiver the call, think of a rabbit being shook about, how he would sound. Also, it may take 15-30 minutes for 'em to show, but it could only take 30 seconds too, so be ready as soon as you start, don't be calling then trying to get better situated or figuting(SP). Once you start calling, move as little as possible, if they catch ya moving, game is up! Good Luck!
