The best and simplest days of Summer require very little:
-Watery things(from buckets full of it to more sophisticated devices).
-Damp Bathing Suits
-Old towels longing desperately to be cut up and used as rags
-Things growing around you (may it be kids, weeds or tomatoes...)
Anything beyond that is either a luxury or comical fodder.
Enjoy it no matter what. Do something yummish.
