Citrus Mint Tea

I live in California's central valley, where, contrary to commonly held perceptions about California, temperatures in the summer soar over 100 degrees, and drop to below freezing in the winter.  Where I live, the closest thing to a beach is a river, and unless you're in that river, being outside in the summer is pretty miserable.  This makes tending the garden pretty difficult at times.  My boyfriend, a San Diego native, hates anything above 80 degrees.  So when temperatures were already at 70 degrees at 9am this morning, he decided we needed to be prepared for the rest of the day.  Enter the second most refreshing drink I've ever had (first place is held by ice water with cucumber slices in it).
