On your next visit to South Padre Island, stop by the Visitor's Center and sign the guestbook! While you're there, select from teh vast array of brochures the ones that suit yoru fancy. Parasailing, camping, eating or just walking on the sand... there's one for you!
To log this cache, post a photo of your GPS next to the guestbook. If your phone is your camera and your GPS, post a picture of your hand signing the guestbook. :)
And don't stay at the Travelodge! It was not very clean.
