In Baltimore we don't light trees, we light monuments. The original Washington Monument is located in Mount Vernon park, the same place where the summer concert series First Thursday takes place. And so each year, on the first Thursday of December, the monument is lit with Christmas lights and we enjoy a display of fireworks accompanied by holiday music. Food vendors from local restaurants set up on the outskirts of the square, and various musicians from the city provide us with a pre-lighting holiday concert.
This year's event was the 40th lighting.
And and added bonus of lasers was part of this lighting. I have such a hard time getting into the holiday spirit in Baltimore, perhaps because cold weather and snow doesn't usually find its way here until January. But usually the monument lighting does the trick. Do you have any particular holiday traditions in your city?
