I made an attempt to get a hold of 4 or 5 former Fort Wayners, who played in my leagues, to get their brief written input on why they left. The one response I did get so far... below, from my facebook, sums it up though:
"Job" is easily the number one reason for anyone college age or above. One engineer, who did not want to move, left for employment in Texas recently. One guy who grew up on a farm and worked at Parkview bluntly told me one reason he left is because he kept getting called back to the family farm to help all the time. But he wanted to move to a bigger city (nightlife) as well. Of course he wouldn't have left if there wasn't a job lined up for him in Chicago.
