i dont use the blocks. i beleive it breaks and hurts the deers teeth. they are not supposed to be eating hard substances. they dont got top teeth just on the bottom how can they chew a peice of the block thats so hard???

di-cal, trace, rock. its the cheapest mineral lick money can buy and it works.

as for the not feedin or puttin mineral out in NY. either the conservation people there are very smart (not to spead CWD) or really stupid.
