How I Can Tell It's High Summer

The Saint John's Wort is in bloom along the driveway.
The neighbor farmer just hayed our field.
The geraniums on the patio have to be watered every day.
The tomato plants are giving off that odd tomato-plant smell.
The wasps are frenzied (they've stung me twice in one week).
The lettuce is bolting.
The supermarket is out of limes.

Happy Fourth, everyone. Throw off some tyrannical bonds and celebrate!
