Summer is hot sometimes. Less often in the northern part of the country. But it is great. Here are some of my reasons why:
Frogs (especially of the giant, wet, and slimy variety)
Snakes--but only the playful kind
Giant house-eating vines with flowers
Bees! and beekeeping, too.
These ones have been in this tree far too long.
Cats, because everybody likes cats
More cat! and a rabbit, and peacocks, all living together but without the eating each other part (we hope)
Deer, of the baby variety
In conclusion, what is great about summer is this: thunderstorms, food, plants, animals, and fun.
