In my opinion, and based on my reading, tax supported short-term entertainment events have no long-term beneficial impact on the local economy, let alone the statewide economy.  Moreover, the benefit only a very limited segment of the economic community and for only a very limited time.  They represent a very "special" kind of Trickle Down economics....the money trickles out of the pockets of taxpayers and into the hands of a very limited special interest group.
