Aransas Pass, the other side of Corpus Christi Channel (they call channels passes here). Port Aransas is the beach town on the island. Aransas Pass is the mainland town. Now we have RV Sites on both sides of the channel. Today we bought an RV lot in a golf course community under development outside Aransas Pass.
