Have been using the Exxon Express Mart on Hiway 6 and Rock Prairie lately and while the gas tends to always be .30 per gallon more than Valero on Harvey Road there are some perks. To begin with if it’s raining, the gas pump canopy has an entire covered over canopy to block rain all the way to the entrance of the store. Have rarely ever seen that intelligence in design with a gas station in the US. It also has large clean public restrooms and a chicken restaurant inside, which apparently used to have a drive thru that is no longer used.
