First item on the agenda was to stop at a battleship. Because it was on the way and Jon loves this kind of stuff.
Next, go to Walmart for a kite.
Then turn into pirates and hunt for treasure (seashells) on the beach, make a fort out of your treasure, bury the fort so no one else will find it, laugh until it hurts, and get insanely sandy.
Then take a nap on the beach.
Then, when the rain really comes down find random indoor activities in Myrtle Beach. Such as:
An interactive aquarium where you can pet a stingray;
A pirate dinner theater owned by Dolly Parton;
And a place that let's you hold baby animals like chimpanzees, wolf pups, and tiger cubs, for a nominal fee.
Jon: "I held a baby monkey wearing UNDIES!"
Like I said, who needs sunshine to have fun on the beach?
But possibly the best part for me was at the end of the day, when we'd put these two tuckered-out puppies in the bed and watch them sleep.
