The future of Old Tucson Studios remains uncertain after the current leaseholder, American Heritage Railways, announced it would not extend its lease with Pima County. Shelton was reacting to the news that American Heritage Railways will not renew a five-year lease option for Old Tucson. That's why she wishes American Heritage Railways would reconsider their plans to stop operating Old Tucson in April. Frisch says there has been confusion after American Heritage Railways put their Old Tucson assets up for sale for $1.5 million. But if not them, she believes someone will come in and take over the operation of Old Tucson.
