For all the outdoor lovers, Lake Anna is a great spot to get out on the water or even just enjoy an evening at The Cove or Tim's on Lake Anna (Local Restaurants)
If you want to enjoy a night out, good restaurants, some nice shops, or even the local farmer's market downtown Fredericksburg might be the place for you.
If you forgot something on the trip down or just want to shop central park is the place for you.
The newly formed Fredericksburg National baseball team makes for a good spot for a night out. In June they may be playing a game or offering a concert series. The attached website will help if you are interested in these events.
