Massive storage tanks for crude oil are being constructed in this field just on the south edge of Cushing. The tanks are owned by Enbridge. Each tank can hold 250,000 barrels of oil. Residents and businesses of Cushing are preparing for the arrival of President Barack Obama this week. The president will make a brief stop at a TransCanada Corp. pipe yard northwest of town, as part of a four-state tour to promote the administration's energy policy. Ruth Ann Johnson, 73, who served 50 years as the town's librarian, said the Payne County community of 8,000 will welcome President Obama on his first visit to Oklahoma after being elected in 2008.
