The only problem I see with the mix is it changes depending on what meats they have butchered each week. So it makes it hard to be accurate on nutrients. But I think if I go with part that, & part 1 protein source, I can be close enough that it won't matter. It' certainly going to save money & I feel safer with a small local butcher than a big grocery for meats.They know where the animal came from & do it all themselves. It will be nice not to have to butcher or grind it all myself.There were a lot of local farmers in there buying.That gives me confidence in them too.Definitely worth the drive for me[40 mins each way].I will look up their # & address & post it with their hours in case anyone wants to call in an order for pickup.If you want the pet ground mix or burger tubes,they grind them Sat am.The rest of the week its frozen.The bags average 8-12 lbs. The ones I got were 12.3,13,4 & 8.2 lbs. It's not far from Rte 73,which is a main highway.To give you an idea of distance,its probably about an hour from Philadelphia.
