What to pack

What January feels like

The Gem and Mineral Show takes over from late January — hotels turn into showrooms, tents go up along I-10, and rooms cost what rooms cost in a city with no vacancy. Nights get cold enough that longtime residents throw sheets over the citrus trees.

Real rain shows up about 2 days all month; the rest stay dry. The air runs dry — whatever the thermometer says, it wears easy.
