Sheri, wife and I used bright red bandanas...they really stood out from the rest of the luggage and no one else used red bandanas. We saved them for our next trip as well, even to use when flying. Have a blast!
PS. you can go to
www.galvestonwebcams.com and see the dock where the Ecstacy is, even watch her go out and come back in. Live web cam!
Have fun!
