It's always tulip time in the Netherlands. Anyone who has flown into Amsterdam's Schiphol Airport on a pre-dawn flight has seen the large structures where tulips and other bulbs are nurtured under 24-hour lights. They are a spooky sight, glowing in the misty darkness. The tulips show up in Amsterdam's canal side flower market. They huddle in paper-wrapped crowds, looking like paints in a set of watercolors. What a bargain! Wouldn't it be fabulous to have fifty of them brightening up our hotel room? If I return to Amsterdam, perhaps I can squeeze a vase into my luggage.
