The National Cherry Blossom festival - I prefer the blossoms at sunrise, but no matter what time you go it is beautiful.
Opening Day - I am not a huge baseball fan but there is something special and hopeful about those early spring games.
Spring Flowers - Little bursts of happiness.
Island Trips - Annual reunion of friends in St. Martin.
Spring Running - not too hot, not too cold.
Farmers markets and festivals
Other things I look forward to in the spring: Daylight Savings Time, annoucement of summer music series at Wolf Trap, washing the last of winter's grime off your car, and packing away all my cold weather gear.
