There is a IPhone app where you type in your zip. and the date prior.
and it automaticly vibrates when hunting opens in the morning or when it closes at night.
ie (it would buzz you at 6:36 when hunting opens in your area and lets you know when it is light enough to legally shoot a animal)
I've heard it is very helpful when you dont quite know if that huge buck is legal to shoot.
But I dont know what this app is called sorry.
