I remember buying Honeycrisps for $1.09/# in SE Wisconsin, back before they got nationally popular. Of course, now that they are popular, they sell for more than $3/# where I currently live, and you can often tell they were grown somewhere other than northern lake country, just because they taste so different. East coast Honeycrisps really are no better than Pink Lady, and if you line up three genetically identical Honeycrisps from Washington, Minnesota, and New York, there is absolutely no question that you will be able to pick out the Minnesota one by taste.
It's like buying low-sulfur onions grown somewhere other than Vidalia, GA. If you know the food well enough, you can sometimes taste the placeness in it.
