This is the exact trend we are trying to prevent in Indiana. A group of us (Amanda Morrison, Amanda Aldridge, Josh Hambright, and myself) are working to make IndianaFIRST a 501(c)3 organization to help to retain the teams in Indiana, start new teams, and bring more attention to the state. Its going to be a long and hard process, but it's defentally going to pay off. If you are interrested in seeing what we are trying to do you can check out
this thread on the IndianaFIRST forums and some of the other treads.
We hope that this will help us to get big corporations behind us and FIRST to help out the less forturnate teams.
