A Perfect Day for Lemonade

It was 90 degrees at our house this afternoon at 5:00. We only get about 3 days a year like this in San Francisco. So we had a picnic in the park for dinner, and when we got home, we made lemonade.

Lemonade:
juice of 5 lemons
1/2 cup sugar (or to taste)
16 ozs cold water

Mix all ingredients together and serve in tall glasses.
