Camera so you can take pics of hunky lifeguards like the one in my TT banner!
Something to drink! (it doesn’t have to be Propel, but extra points if you do because it’s so yummy!)
Sunscreen! (the higher the spf, the better!)
A red-hot read! (it doesn’t have to be one of mine, of course, but lots of extra points if it is – although if it is, you might have to bring vibrator, too – just make sure it’s small enough to be discreet!)
