I'm in Port Aransas three to four times a year hanging out at a buddies beach house - we end up cruising the beach, playing soccer and beach volleyball by day and hanging out listening to music and building bonfires at night. Growing up, we used to do the same on Bolivar Island, but Ike pretty much wiped it off the face of the earth so I don't know if anyone goes out there anymore. Port A is a great weekend destination for the summer with 6.3 miles of beach you can drive, camp, etc. on (there are lots of nice hotels down there, too). It's really rowdy for Memorial Day, etc.
