‘Tis the season for ghosts, ghouls, goblins and, of course pumpkins. It seems the latter is everywhere, pervading coffees, pies, even cereal. (Have you been to Trader Joe’s lately?!) Perennial pumpkin fun abounds around the D.C. region. Farms transform into playgrounds full of fall frills, such as hayrides, giant slides and pick-your-own future jack-o-lantern. Whether you’re looking for straight pumpkin pickin’ off the vine or something with activities to kill a day with, there’s a farm or festival to meet all tastes.
