This Enco gas station on the northwest corner of Ina Road and the Florence Highway (now known as Oracle Road) featured some shrubs and a picnic table, which apparently were the latest thing in 1968. Note the old service station across the street at Casas Adobes Plaza. Most recently that building was the Einstein's Bagels and Starbuck's Coffee. It was torn down in 2013 for the parking lot expansion for the new Whole Foods. Also note the empty lot on the southeast corner. That is now the Safeway plaza.
