huntingbry,
if there are nonatural salt/mineral licks in your state, they deer wont react the way you would think to your mineral lick. now if PA is like MO, where theres no natural salt or minerals. you will have deer comming from miles around. they fein for salt and minerals. and remember they never forget where its at! so when momma doe and her 2 button bucks come and eats the minerals the 1st year. those bucks will come back every year!!
