Go to the beach, lake, waterfall, river...
Fly your kite high
Ride your bike
Walk barefoot around the house
Take cold shower
Dry clothes in the sun
Eat watermelon
Cook out
Sleep out
Eat out
Watch birds in the backyard
Count the butterflies
Grow some vegetables
Lie down under open skies, enjoying the clouds
Lie down under open skies, counting the stars coming by
Look at the birds that fly by, nest around...
Do not miss the moon as it grows
Live without the air condition as much as possible
Walk, walk, walk wherever possible, whenever possible
Drive with windows down
Go fishing
Don't miss the mangoes
Have fun overall...Summer doesn't last for long... Please feel free to add yours to the list...
