I think people are finding that when they move without contacts to a new area...the great
paying jobs just aren't there as hoped for...especially in a University town when so many
have degrees and advanced degrees.   I have met several grads and those with even advanced degrees who are working at the grocery stores and are grateful to have a steady job.
That is just the economics of our country right now.
   
Also, new folks who move here during the summer may not be able to handle the many 
months of grey weather and rain.
