Farmer in the Dell I'm not

So as many are aware we have 3 very low growing crab apple trees in our yard.  Since it is now apple pickin' time my kids have been BEGGING to pick our apples.  So the other night with a small cooler and garbage bags we start pickin' our fruit.  Now, as those of you who may know my children are very exuberant beings.  Kid #1 is singing some made up pioneer song at the top of her lungs and Kid #2 and 3 are at another tree slam dunking there harvest.  If this was our living we would be absolutely broke because we don't have what it takes.  We salvaged about 50 tiny apples out of about 300 and we will be making them for a "tasty" treat during FHE.  Can crab apples poison you?  If you don't hear from me call poison control or 911.  Wish me luck!
