In case anyone is wondering how much money visitors are bringing to Texas as they descend on the Hill Country to view Monday’s eclipse, a San Antonio college professor has crunched the numbers. Bülent  Temel, a political economist at UTSA, estimates that tourism to witness the celestial event will dump between $150 million and $603 million into the state’s economy, radio program The Texas Standard reports. Tumel previously called the eclipse “the most profitable 22 minutes in Texas history.”
